Huff Post: By Daniel Cox: The religiously unaffiliated are an increasingly important part of the American religious and cultural landscape. They account for nearly 1-in-5 American adults, and although they turn out to vote at lower rates than other religious groups, they are having a profound effect on American electoral politics, accounting for one-quarter of Obama’s vote in the past election.
Yet, although the politics of the unaffiliated — comparatively liberal on cultural questions and increasingly Democratic in voting preferences — suggest that they are a fairly homogenous group, there are actually three subsets among the unaffiliated that are demographically and socially distinct. In 2012, the American Values Surveyidentified three distinct groups among the unaffiliated: secular Americans (39 percent), self-identified atheists and agnostics (36 percent), and unattached believers (23 percent). The accompanying report detailed the significant religious differences between these groups, but there are major socio-economic differences separating them as well.
Atheism is not only for the upper class people, but
upper class people tend to be more arrogant and smug ,low class people have more common sense and modesty so as long as they believe in the cultural values of religion they will not proudly declare themselves atheists.
