Replying to Reddit Atheists

I was wondering if I'm the only one that just gets annoyed with the whole /atheist circle jerk fest that goes on 24/7 365 on Reddit. I'm wondering what the appeal of being a complete asshole to anybody that has faith in a religion that you don't support is. This isn't me trying to start a shitstorm, I'm just curious if anybody has any opinions on this. Like does everybody that isn't a hardcore asshole just ignore their posts, and that's why there's no opposition? I'm not saying all atheists are assholes either, anytime shit starts it's usually an aggressive theist vs an aggressive atheist, so don't call me a dick.
