I've seen some legitmate complaints recently about hostility to religion by some on the left. Not all Christians are represented by Pat Robertson and his ilk - in fact, the majority are not. So you are an atheist. Good for you - you've got your sacred cows, too.
The reason I mention this is that in mocking theocrats in America, people sometimes refer to swaths of the country as "Jesusland". This is unnecessarily offensive to non-theocratic Christians. The theocrats are in need of mockery, still.
So I offer you what appears, by googling, to be an original coinage: Churchistan.
Isn't that better?
