@mattsheffield Agreed. The ongoing joke amongst certain religions is that atheism is a religion, which I disagree with, but certain forms of atheism do feel cultlike, which I suspect leads to eager adherence to anything with even a veneer of "empowering the self"
Add to this the kind of "immature atheism" (I've been there) which is really just "I'm angry at religion and my former deity and need to prove it" and you have a potent combo.
