I couldn't care less about political correctness. I'm an atheist, yet I also defend the rights of individuals to subscribe to any faith they choose, not for political correctness but because it's the right thing to do. It's only when people try to foist their religion onto others that I will call foul.
Note that this doesn't mean I won't point out the fallacies of those religions when called for. I'm a firm believer in, "If you're willing to stick it out there, I'm willing to spank it!" (You ladies get that? It's not just a religious thing, you know!)
