I should shout out one of my favorite sociology articles in recent years:
Penny Edgell, Joseph Gerteis, and Douglas Hartmann, “Atheists as ‘Other’: Moral Boundaries and Cultural Membership in American Society,” American Sociological Review 71 (2), 2006.
The authors use survey evidence to demonstrate that as tolerance for religious diversity grows, it does so at the expense of non-believers.
The article is available from Gerteis’s website here (.pdf).
