Neither one nation, nor under God
In 2008, American religion is inextricably linked to social conservatism and the political right
Some 44% of Americans reject the theory of evolution but I've never met any of them. I don't know many churchgoers because I live in an urban-coastal area far from the "pro-America areas" of the continent, commended by Sarah Palin, where most reside.
I belong to the fastest growing "religious group" in the US, the 100-million strong unchurched and, as a "knowledge worker" have little contact with members of the pro-American diaspora. We occupy the same geopolitical landmass, but during the Big Sort of the late 20th century, became different nations. Citizens of my nation are socially liberal, politically left and, above all, secular because, in 2008, religion is inextricably linked to social conservatism and the political right.
In 1965, religion in America, as Americans understood it, would have been readily intelligible across the Atlantic. Mainline churches dominated the landscape. Americans expected everyone to be religiously affiliated and regarded religion as beneficial, or at least innocuous. The gothic revival church was America's religious icon and, regardless of their own religious beliefs or practices, paradigmatic Christianity for most Americans was an ecumenical faux-Anglicanism resembling the as-yet-unreconstructed Songs of Praise.
Twenty years later, American religion had undergone a paradigm shift. The icon of American religion was the evangelical mega-church, where televangelists preached to thousands in situ and multitudes of TV viewers. Americans, irrespective of their own religious beliefs or practices, regarded American-style fundamentalism as paradigmatic religion.
