I personally don't really get how someone reconciles materialism with religion, but why be an obnoxious atheist about it? I'd rather not exclude anyone because of my idealistic worldview; either I'm wrong and religion will exist for as long as humanity does (so what did I accomplish by being a dick about it?) or my way of thinking is correct and people are going to come around to that eventually, once the material conditions are right for people to no longer need religion.
