INTRODUCTION
“There's probably no God. Now stop worrying and enjoy your life.” Buses with these words drove around London and other British cities from the beginning of January 2009. It was the start of a British atheistic campaign, later also launched in the United States, Canada, Australia, New Zealand, Brazil, Italy, Spain, Germany, Ireland, Finland, Sweden, and the Netherlands. Even though these campaigns aroused considerable media attention in most of these countries, this assertive type of “new atheism” and its social and cultural support bases are only beginning to be explored (Amarasingam Reference Amarasingam2010). This is because students of religion have traditionally treated “non-religiousness” not so much as a domain of systematic empirical study, but rather as one of speculation. Some assume for instance that the predominant attitude toward religion in today's massively secularized Western European countries is not so much one of hostility, but rather of disinterest (Bruce Reference Bruce2002), whereas others tacitly assume that non-religiosity logically and inevitably manifests itself as rationalist anti-religiosity (Stark, Iannaccone, and Finke Reference Stark, Iannaccone and Finke1996).
Remarkably, then, students of religion have made major efforts to compare religious traditions and to study how the latter are shaped and transformed by the historical, social, and cultural circumstances they find themselves in, but a similar sensibility to specificity, particularity and variation is hard to find when it comes to non-religiosity. One consequence is that people without religious beliefs are often referred to as “atheists” (Becker and Vink Reference Becker and Vink1994; Norris and Inglehart Reference Norris and Inglehart2004, 186), even though research in the United States by the Pew Forum suggests that the latter label has narrower connotations than “non-religiosity.” Only about a quarter of those who are non-religious are willing to identify themselves as “atheists” and the remaining three-quarters reject this label.Footnote 1
Ribberink and Houtman (Reference Ribberink and Houtman2010) refer to processes of “coming out” as an atheist (Smith Reference Smith2011) as processes of “deprivatization of disbelief.” They note that in the Netherlands more and more disbelievers appear to express anti-religious sentiments on web-blogs and social media and to argue for a removal of religion from politics and the public domain. These disbelievers have, hence, apparently transformed an indifferent “non-religiosity” into an assertive “anti-religiosity.” The study of such processes of deprivatization of disbelief necessitates the application of a distinction between private and indifferent “non-religiosity” on the one hand and public and assertive “anti-religiosity” on the other. Such an opening up of the traditional catch-all category of the non-religious “leftovers” for critical empirical scrutiny (Baker and Smith Reference Baker and Smith2009a; Reference Baker and Smith2009b) is especially important, because assertive anti-religiosity has more potential for political mobilization against public manifestations of religion than indifferent non-religiosity.
Against this background, we study how this type of “anti-religiosity” can be explained, with special reference to the role of national religiousness. Our study thus feeds into the more general debate on how religious and secular fundamentalisms and violence shape the late-modern societies of the 21st century (Calhoun, Juergensmeyer, and VanAntwerpen Reference Calhoun, Juergensmeyer and VanAntwerpen2011; Achterberg et al. Reference Achterberg, Houtman, Aupers, de Koster, Mascini and van der Waal2009). We focus on Western Europe, because it is there that we find on the one hand some of the most massively secularized countries of the world (particularly in the North West, e.g., Scandinavia, United Kingdom, the Netherlands) and on the other hand countries where religion has retained much more of its former foothold (particularly in the South West, e.g., in Catholic countries such as Spain, Portugal, and Italy) (Martin Reference Martin2005). We start with an elaboration of two theories that both relate anti-religiosity to national religious contexts, the rationalization theory, and the deprivatization theory, but that do so in strikingly different ways. We then discuss our data and measurements, test the relevant hypotheses, and summarize and discuss our findings.
EXPLAINING ANTI-RELIGIOSITY: THEORY AND HYPOTHESES
There are two major theories that may be able to explain anti-religious attitudes. On the one hand, there is a long intellectual tradition that can be called the “rationalization theory.” It understands reason as the ultimate authority and religion as an irrational force, so that the unfolding of the former stimulates not simply non-religiosity, but anti-religiosity (Campbell Reference Campbell1971). On the other hand, we bring forward a strand of theory that we call the “deprivatization theory,” which leads to predictions that are diametrically opposed to those that can be derived from the rationalization theory. This is because it understands anti-religiosity as evoked by a massive public presence of religion (Cimono and Smith 2007; Stahl Reference Stahl2010), whereas it associates indifferent non-religiosity with secularized contexts (Taylor Reference Taylor2007, 12–13). In what follows, we discuss both theories in more detail to derive the hypotheses that need to be tested to ascertain their empirical validity.
Anti-Religiosity as the Outcome of Rationalization
The notions that there is no God and that religion is a false idea have often been grounded in rationalist convictions, central to which is a firm adherence to reason and science, as for instance in Kant, Marx, and Freud.Footnote 2 Campbell (Reference Campbell1971) describes how this has led to the development of a range of “rationalist” movements in the 19th and 20th century, with rationalist societies, rationalist papers, rationalist press associations, and so on and so forth. This line of thinking has deeply influenced the social-scientific study of religion, especially in classical sociology, where Durkheim, Weber, and others expected a growing influence of rational thinking in modern times to contribute to the demise of religion (Durkheim Reference Durkheim1969, 291Footnote 3; Weber Reference Weber, Gerth and Mills1991 [1920]). Stark, Iannaccone, and Finke (Reference Stark, Iannaccone and Finke1996, 436; italics in original) point out that some sociologists refer to rational thinking not only as the reason for why people do not become religious, or stop being religious, but even for becoming anti-religious:
For many leading scholars, religion was not so much a phenomenon to be explained as it was an enemy to be overcome. Starting with the assumption that religion is false, and thus less rational than other behaviors, these scholars employed unique theoretical principles to explain (and dismiss) it and, above all, to pronounce its inevitable demise.
This notion that reason inevitably defines religion as its enemy and will eventually undermine it has meanwhile been extensively critiqued. For one thing, Stark and Finke (Reference Stark and Finke1999) have argued against the notion that religion is irrational and cannot be explained rationally. Instead, they refer to rational behavior as the principal reason for why people are religious. For another thing, it has been argued that we increasingly live in a post-modern world, where not only religion, but also science has lost much of its former aura and plausibility (Davie Reference Davie2007, 95; Houtman and Mascini Reference Houtman and Mascini2002; Inglehart Reference Inglehart1997, 79). Despite these critiques, rationalization theory continues to inform studies aimed at the explanation of disaffiliation from religion until the present day. These studies typically conceive of rationalization and religion as communicating vessels, measuring the former as level of education (at either the individual, country, or historical-period level) and assuming it to be hostile to and undermining the latter (Te Grotenhuis and Scheepers Reference Te Grotenhuis and Scheepers2001, 594; Baker and Smith Reference Baker and Smith2009a; Need and De Graaf Reference Need and De Graaf1996; Ruiter and Van Tubergen Reference Ruiter and van Tubergen2009).
This rationalization theory has clear implications for where we should expect to find most anti-religiosity. Given the assumed incompatibility of reason and religion, anti-religiosity is seen as the logical outcome of the spread of reason and the concomitant decline of religion, so that disbelievers in the least religious countries should be more anti-religious than disbelievers in more religious (“less rationalized”) countries. This informs the hypothesis that in countries with lower levels of religiosity, disbelievers will feature higher levels of anti-religiosity than in countries with higher levels of religiosity (Hypothesis 1).
A central tenet of the rationalization theory is that scientific and technical progress will gradually make the world a more rational place, with the expansion of mass education in the 20th century understood as the major vessel of this process. Because rationalization is seen as a gradually but ultimately inevitably unfolding historical process, disaffiliation from religion becomes ever more likely, which shows up in differences in religiosity between birth cohorts (Te Grotenhuis and Scheepers Reference Te Grotenhuis and Scheepers2001, 603):
This has nothing to do with growing older (an age effect), for it is related to the fact that people born in the 1930s and 1940s experienced much lower levels of rationalization during adolescence compared to people born in the 1970s and 1980s.
Because of its tenet that rationality and religion are incompatible, so that non-religiosity takes the shape of anti-religiosity, the rationalization theory predicts that in countries with lower levels of religiosity (more “rationalized” countries), younger birth cohorts will feature higher levels of anti-religiosity than older birth cohorts (Hypothesis 2).
Finally, the assumption that an individual's level of education reflects the degree to which he or she has been exposed to rationalization (Ruiter and Van Tubergen Reference Ruiter and van Tubergen2009) applies of course particularly if he or she has received his or her education in a less religious (“more rationalized”) society. This means that the rationalization theory also predicts that in countries with lower levels of religiosity, the higher educated will feature higher levels of anti-religiosity than the lower educated (Hypothesis 3).
Anti-Religiosity as the Outcome of Deprivatization of Disbelief
A second explanation of anti-religiosity focuses on religion's power to define what is “normal” and what is “deviant” in more and less religious national contexts. Until the 1960s, in all of the Western European countries under study here, being non-religious was an identity that needed to be defended or at least accounted for. Most Western Europeans were connected to a religious institution of some sort, the church had a major influence on politics and society, and the small number of non-religious people was firmly connected to anti-establishment and anti-religious institutions (McLeod Reference McLeod1997). Being non-religious at the time meant that one had to make a conscious decision to deviate from bourgeois conventions, and this generally meant that one needed to opt for a position that was more anti-religious than non-religious. This has changed since the 1960s and 1970s, when the Christian churches and Christian religion declined in adherence as well as public significance in all Western European countries, albeit of course in different degrees. In the process, religion lost much of its former taken-for-granted public role, the discursive power of the religious institutions declined, and being non-religious became a more viable option, less subject to social sanctions than before. This means that it became easier to adopt a non-religious position that was less necessarily an anti-religious one. In fact, many Western Europeans did not even face the need to actively “choose” to become non-religious any longer, because religion lost its is “natural” and self-evident character, so that it was hardly needed anymore to defend or justify a non-religious position (Taylor Reference Taylor2007, 12).
Our second theory about the relationship between national religious context and anti-religiosity suggests that the existing cross-national variation in the public presence, visibility and vitality of religion does not remain without consequences, but evokes differences pertaining to “deprivatization of disbelief.” More specifically, it predicts that disbelievers in countries with low levels of religiosity are less anti-religious than disbelievers in countries like the United States, where religion is virtually omnipresent — a possibility that is at least hinted at in articles by Hout and Fischer (Reference Hout and Fischer2002), Edgell, Gerteis, and Hartmann (Reference Edgell, Gerteis and Hartmann2006), and Baker and Smith (Reference Baker and Smith2009b). The deprivatization theory hence predicts that in countries with higher levels of religiosity, disbelievers will feature higher levels of anti-religiosity than in countries with lower levels of religiosity (Hypothesis 4), which is the mirror image of the hypothesis derived above from the rationalization theory.
In this case, too, formative experiences of having grown up in a more religious or a more secular society, do logically make a difference. When someone has been born in the first half of the 20th century, he or she has grown up in a context where most people were a member of a religious institution and where religion had a major influence on culture and politics. In the 1960s, large numbers of young people (who are today's older generation) choose against this and actively disaffiliated from the churches for a wide range of reasons (Streib and Klein Reference Streib and Klein2012). Because of this, today's older birth cohorts will feature higher levels of anti-religiosity than younger ones, because the latter have grown up in a secular context that the former has not experienced during its formative years. Indeed, research by Ecklund and Scheitle (Reference Ecklund and Scheitle2007) and Sherkat (Reference Sherkat2008, 542) suggests that this generational difference does not exist in the United States, presumably because it has remained a much more religious country since the 1960s. Be this as it may, the deprivatization theory predicts that in countries with lower levels of religiosity, older birth cohorts will feature higher levels of anti-religiosity than younger birth cohorts (Hypothesis 5). Note that this hypothesis once again contrasts with the hypothesis derived above from the rationalization theory.
Finally, unlike the rationalization theory, the deprivatization theory does not assume that a high level of education is incompatible with religion because of their inherent “rationality” and “irrationality,” respectively. What it does assume, is that the high educated will oppose religion and rejected it if it constitutes an obstacle to individual liberty and acceptance of cultural difference. According to any number of studies, after all, a high level of education is one of the major sources of cultural and political tolerance in the Western democracies (Houtman Reference Houtman2003) and there are no good reasons to assume that this is any different for tolerance of religion. Indeed, Bruce (Reference Bruce2002, 117) suggests that the relativism that is induced by higher education extends to tolerance of religion, so that a high level of education leads not so much to anti-religiosity, but rather to religious indifference. Again in contrast to the rationalization theory, then, the deprivatization theory predicts that in countries with lower levels of religiosity, the higher educated will feature lower levels of anti-religiosity than the lower educated (Hypothesis 6).
Hypotheses
Both of the theories about anti-religiosity that we have discussed above relate anti-religiosity to national religious contexts, but they do so in strikingly different ways. All three hypotheses derived from each of them are contradicted by the three derived from the other. They predict the highest levels of anti-religiosity for disbelievers as compared to non-disbelievers in respectively the least (rationalization; Hypothesis 1) and the most religious countries (deprivatization; Hypothesis 4). They predict stronger anti-religiosity among respectively the younger (rationalization; Hypothesis 2) and the older generation (deprivatization; Hypothesis 5) in the most secularized countries. Finally, they predict stronger anti-religiosity among the higher than among the lower educated in respectively the least (rationalization; Hypothesis 3) and the most religious countries (deprivatization; Hypothesis 6).
Data and Operationalization
In order to be able to test these hypotheses, we have used the dataset of the International Social Survey Program: Religion III (ISSP 2008). The ISSP 2008 dataset is optimal for our research purpose as it contains questions that focus on respondents' attitudes to religion and religious people. As we are interested in anti-religiosity in countries where religion is thought to be disappearing, we focus on Western Europe. In the discussion on the decline of religion in some regions and the resurgence of religion in others, Western Europe is commonly seen as “the odd one out” (Martin Reference Martin2005, 47; Berger Reference Berger1999; Greeley Reference Greeley2003). Unlike in other Western countries, such as the United States, in most Western European countries the church has lost most of its former strength, adherence, and influence. This provides a very interesting background for the study of the dynamics of anti-religious attitudes as a product of rationalization or as a deprivatized reaction against religion. For this reason, we selected the data from 14 countries in the ISSP dataset that are located in Western Europe (N = 23,567). These countries are: Austria (AT), Belgium (BE), Denmark (DK), France (FR), Finland (FI), Great Britain (GB), Ireland (IE), the Netherlands (NL), Norway (NO), Portugal (PT), Spain (ES), Sweden (SE), Switzerland (CH), and Germany (DE).
The national church attendance is measured as the share of people going to church at least once a month or more in a particular country.
Anti-religiosity is measured by a scale tapping the respondents' attitudes toward religious influence on public life. Largely based on Bruce (Reference Bruce2011, 221) who used the same data, we used four questions that were straightforwardly asking for people's views on the influence religion may have on the public domain. Two of these ask for the attitude of the respondents toward religious leaders influencing government's decisions and peoples' votes. The other two questions ask for response on statements about intolerance of religious people and whether religion creates conflict or not.Footnote 4 We linearly combined the four abovementioned Likert items, with answer categories ranging between 1 (strongly agree) — 5 (strongly disagree), that together yield a reliable scale (Cronbach's α: 0.72, see Table 1). Normally, the lower scores would indicate agreement with anti-religious sentiments. We reversed this scale, so that higher scores indicate higher levels of anti-religiosity. Scores that were not on the scale of 1–5 were coded as missing.

Disbelief is measured by looking at those people who answered the question what describes best their belief with “I do not believe in God.” They were labeled “disbelievers” (=1) and the others were labeled “non-disbelievers” (=0). The latter are not to be called believers, since this group also includes agnostics, people that are not sure what to believe, and those who belief in “a higher being.” Between 0% (Austria) and 5.5 % (Belgium) of respondent were missing on this variable.
The different birth cohorts are coded into three groups. People born after 1974 are coded as young (age 15–34 years, 26.5% of respondents), people born between 1959 and 1973 are coded as middle (age 35–54 years, 36.4% of respondents), and people born before 1958 are coded old (age 55+ years, 37.1% of respondents). Education is measured as the number of years people were enrolled in full-time schooling.
The two theories that can explain anti-religiosity as described above, led to three hypotheses that focus on disbelief, birth cohort, and level of education. Other literature suggests that there are more variables that are related to attitudes toward religion. These are marital status and gender (Bainbridge Reference Bainbridge2005; Ecklund and Scheitle Reference Ecklund and Scheitle2007; Miller and Hofmann Reference Miller and Hoffman1995; Miller and Stark Reference Miller and Stark2002). Marital status has the values (1) Married (54.2%), (2) Widowed (7.6%), (3) Divorced (7.3%), (4) Separated (1.9%), (5) Not/Never Married (25.9%). Of all respondents 3.3% did not answer this question and were coded as missing. Gender has the values (1) Male (46.4%) and (2) Female (53.6%). We use these variables as control variables to test our model.
RESULTS
Before we start testing our hypotheses, first, we will look at where we can find the highest levels of anti-religiosity. Figure 1 presents the average level of anti-religiosity (y-axis) as a function of the level of national church attendance.

Figure 1. Predicted mean anti-religiosity and national church attendance per country for 14 Western European countries, Source: ISSP 2008.
Figure 1 shows that anti-religiosity is most prevalent in the more secularized countries and least prevalent in the highly religious countries. There appears to be a very simple correlation between the level of national church attendance in a certain country and the average anti-religious attitude in that country: The more religious a country is, the higher its religious tolerance and vice versa. This is not surprising. However, even if there is a direct correlation between low levels of national church attendance and anti-religiosity, we have no answer to the question if lower levels of church attendance is the variable that explains anti-religiosity best or if there are other variables that correlate stronger with anti-religiosity. Through a discussion of two theoretical paths, we have come to two sets of opposing hypotheses that helps us answer this question.
We used ordinary least squares linear multilevel analysis with maximum likelihood estimation for two reasons to test these hypotheses. First and foremost, multilevel analysis allows one to simultaneously estimate effects of individual-level variables, and of country-level variables. As our data is structured in such a way that there are two levels, 23,567 individuals with certain characteristics (e.g., birth cohort, disbelief, etc.) are nested in 14 countries with certain characteristics (national church attendance); multilevel analysis is the most suited option. Second, as our hypotheses aim at investigating how individuals react differently to different country-level church attendance, multilevel analysis, which allows for the estimation of two equations, one for the main effects and one for the slopes of the effects, is very suited as it allows for testing cross-level interactions. For each set of hypotheses, we ran a separate model estimating so-called fixed effects. These are effects of the variables at either individual or national level, or the interactions between them. Each of the models also contains so-called random effects. These random effects, noted as deviances, are estimations of the variance of the intercept of anti-religiosity which show that the level of anti-religiosity varies across countries. Also, there are estimations of the variances of the slopes of disbelief, age and education showing that the effects of these variables in model 1, 2, and 3, respectively, vary across countries as well. Unfortunately, the N at the highest, national, level is rather limited (14) so we cannot estimate an unlimited number of covariates in our models. Table 2 shows the results of our analysis, which will be discussed below.Footnote 5
Table 2. Explaining anti-religiosity (OLS multilevel analysis, Maximum Likelihood, N = 23,567 in 14 countries)

~p < −0.10; *p < 0.05; **p < 0.01; ***p < 0.001 (one-tailed test for significance).
Table 2 shows a number of effects of the variables on anti-religiosity. As said, we included a number of interaction effects, each of them testing another set of opposing hypotheses. To enable interpretation of these effects, we plotted each of these effects in a figure. In Figure 2, we find a visual presentation of the fact that disbelievers have higher levels of anti-religiosity than non-disbelievers. Second, and more importantly, it shows that relative to the non-disbelievers, disbelievers have higher levels of anti-religiosity in the context of high national church attendance. Although it is true that the general level of anti-religiosity in secular countries is higher than in religious countries (which may be predicted by rationalization theory), the effect of religiosity on the anti-religiosity of disbelievers relative to non-disbelievers is more relevant to us (and confirms deprivatization theory). Therefore we confirm Hypothesis 4 (deprivatization) and refute Hypothesis 1 (rationalization).

Figure 2. Predicted anti-religiosity for Non-Disbelievers and Disbelievers in contexts of low and high national church attendance in 14 countries, 2008.
The second set of opposing hypotheses concerns the relation between the religious context of a country and the influence of birth cohort on anti-religiosity. Here we predicted that if the rationalization theory is right, in a context with low levels of national church attendance, people from younger birth cohorts will have higher levels of anti-religiosity. Deprivatization theory would have it the other way around (higher levels of anti-religiosity for older birth cohorts in context with low levels of national church attendance, Hypotheses 2 and 5 respectively). From Table 2 we can see that when we look at the influence of birth cohort on anti-religiosity, we see that it has limited influence. In general, older people tend to be more intolerant toward religion than younger people. In Figure 3, the influence of the variable birth cohort on the predicted anti-religiosity is presented in the context of low and high national church attendance. Here we see that the older birth cohort is very much affected by the religious context. We see that older cohorts tend to be relatively less anti-religious in a context of high national church attendance. This illustrates how national church attendance is important for analyzing the influence of birth cohorts on anti-religiosity, because the rationalization hypothesis would have had it the other way around. When we compare birth cohorts in the different contexts, we see that the deprivatization hypothesis fits better with our findings. The effect of the religious contexts on the older birth cohorts is as we expected based on the deprivatization theory (disaffiliation of earlier generations leads to higher levels of anti-religiosity in contexts with low levels of national church attendance). It is also in line with the deprivatization theory that younger cohorts would be less anti-religious in contexts with low national church attendance, since they have no need for being intolerant to a religion that they hardly notice. Research done by Ecklund and Scheitle and Sherkat suggested that younger generation are less anti-religious than the middle birth cohorts. This is confirmed by our findings.

Figure 3. Predicted anti-religiosity for three age cohorts in contexts of low and high national church attendance in 14 countries, 2008.
The third set of hypotheses predicted the influence of education on anti-religiosity. Here we would expect that in a context with low levels of religiosity, people with higher levels of education will be more anti-religious, according to the rationalization theory (Hypothesis 3). Hypothesis 6, derived from the deprivatization theory, says the opposite. Table 2 shows that the variable education in itself does not correlate with anti-religiosity strongly. Looking at the combination of the variable education and national church attendance, however, we see major differences occur. Figure 4, which again illustrates the interaction-term found in the multilevel analysis, shows how higher educated people in a climate of high national church attendance are far more anti-religious than their counterparts in countries with low religiosity. Also, for people with a low level of education, in a country with low levels of national church attendance there is a higher score on level of anti-religiosity, than in countries with higher levels of national church attendance. We see that the religious context has a major impact on how anti-religious people from different levels of education are. Both for the higher educated (who are highly anti-religious in religious contexts, but not in non-religious contexts) as for the lower educated (who are highly anti-religious in non-religious contexts, but not in religious contexts). This influence of religious context on anti-religiosity of the higher and lower educated is exactly as we expected from the deprivatization theory point of view. Thus Hypothesis 6 (deprivatization) is confirmed and Hypothesis 3 (rationalization) refuted.

Figure 4. Predicted anti-religiosity for lower educated and higher educated in contexts of low and high national church attendance in 14 countries, 2008.
To sum up, our analysis shows that all three hypotheses from the deprivatization theory can, by and large, be confirmed and that we did not find much empirical evidence supporting the three rationalization hypotheses. At the same time, this analysis answers the question what conditions will make non-religious more likely to have an anti-religious attitude. Our findings demonstrate that religion matters to disbelievers a lot, but they have relatively higher anti-religiosity rates then non-disbelievers in a context of high religiosity. In the findings on the role of education on anti-religiosity, we discovered that it is the context of high or low levels of religiosity that influences the outcomes significantly.
CONCLUSION
We started this article with the presentation of atheistic bus campaigns and the debate on “new atheism” that has intensified over the last couple of years. However, instead of joining this debate with another opinion, we wanted to address the question on how these anti-religious ideas resonate with the people in the streets of Western Europe. We focused on two theories that brought up a possible explanation for the anti-religious zeal in Western European countries and investigated under what conditions people without religious beliefs will grow an anti-religious attitude. The analysis presented above shows that anti-religiosity does resonate well with people in the streets of Western Europe. However, it does so more, with disbelievers in highly religious contexts, preferably when they are younger and higher educated. In the streets of the countries with lower levels of religiosity, the older, lower educated disbelievers are attracted to anti-religious ideas. The deprivatization theory offered the best theoretical framework to assess these differences. The bottom-line of this theory is that anti-religiosity is not something that comes with either age, disbelief or education, but it is the context of religion that triggers this reaction.
We have focused our attention on Western Europe, but we think that this analysis of anti-religiosity is relevant for the study of what is currently happening in the United States as well. Here, atheists (as a specific group of disbelievers) are seen as immoral and dangerous for the national values (Edgell, Gerteis, and Hartmann Reference Edgell, Gerteis and Hartmann2006), but they are more and more finding ways to establish their identity as a minority over and against the more fundamentalist religious groups (Cimino and Smith Reference Cimino and Smith2007; Davie Reference Davie2007, 95; Hout and Fischer Reference Hout and Fischer2002; Stahl Reference Stahl2010). This is a kind of conflict that fits with the politicized “cultural war” idiom that is common usage in the United States (Hunter Reference Hunter1991). Our analysis indicates that anti-religiosity in the first place is a reaction against religion. It would be interesting to see what kind of religion is the trigger in this cultural conflict and if this “cultural war” is something only the higher educated and the cultural elite are part of (like Campbell (Reference Campbell1971, 96) describes discussing humanism in Britain), or if this is a broader cultural conflict with other social classes in society as well.
For Western Europe, our conclusions are relevant to the debate on the cultural conflicts that arise from what has been called the “twin maladies of modernity” (Achterberg Reference Achterberg2006; Houtman, Aupers, and de Koster Reference Houtman, Aupers and de Koster2011; Zijderveld Reference Zijderveld2000). With the falling apart of institutional “plausibility structures” (Berger Reference Berger1967), more and more people feel alienated and experience a sense of anomie. This has also implications for the non-religious Westerners (Campbell Reference Campbell2007). Our findings show that especially the education one has had influences how people react to this situation. Recently Kronjee and Lampert (Reference Kronjee and Lampert2006, 194) and Ribberink and Houtman (Reference Ribberink and Houtman2010, 222) hinted at the possibility that the lower educated would be a new group with anti-religious sentiments in the Dutch society. Our findings confirm these inclinations. More research should be done to exemplify and expand our understanding of this relationship and to find out what exactly motivates the lower educated to take up this intolerant position toward religion. We would expect that it does influence their voting behavior (for example, through anti-Islamic populism), where they want to live (not in areas where people live with other religious values) and how they express themselves online. An example of such a cultural conflict over political and religious identities is the case of Anders Breivik, the Norwegian mass-killer. Although he refers to himself as a Crusader, actually his hatred was pointed toward the (in his words) anti-individualist, pro-Islamic/anti-Jewish, and cultural Marxist/multicultural politics of Norwegian and European governments and politicians.Footnote 6 He and other Right-wing extremists position themselves as conservative, Christian as well as Secular Europeans against the influx of Muslim culture. The relation between this anti-religiosity (anti-Islam in this case) and the perceived threat of national and individual identities in a multicultural setting should receive more attention by sociologists. It can help us understand the way our societies accommodate differences in values and opinions, be they religiously or politically inspired.
An interesting expansion of our research would be to see if there is a correlation between the growth of anti-religiosity and the decline of religious adherence over time. We would expect that the outcome of anti-religious action might as well be religious tolerance in some countries as a revival of religion in others (a kind of “purified” religion). Barro and McCleary (Reference Barro and McCleary2005) demonstrate that the result of the anti-religious agenda of Communism has had a short term effect. Stalin tried to extinguish religion, but 10–15 years after the collapse of the Soviet Union, religion has made a huge comeback in many ex-Soviet countries (Froese Reference Froese2008; Greeley Reference Greeley2003). The authors of “new atheism” also clearly advocate an anti-religious agenda. Is this anti-religiosity of the higher educated in religious countries a harbinger of a decline in religion? And could this lead toward a situation of non-religion? On the other hand, if it are the younger higher educated disbelievers that become more and more anti-religious, as some authors already noticed for the younger religious groups (Roeland et al. Reference Roeland, Aupers, Houtman, de Koning and Noomen2010; Stahl Reference Stahl2010), this could lead to serious cultural conflicts as well. Our findings suggest that over time, when the influence of religion decreases, and birth cohorts grow, this might lead to religious tolerance. More longitudinal research should be done to see whether a climate of religious intolerance really affects religious growth in a positive or negative way. Also this kind of research can help us to see if there is a tendency towards secular-religious polarization in the more secular countries, or a growing tolerance between religious and non-religious groups.
