Let's not forget about the rivalry with their sibling category, Polls & Surveys (P&S). The sections often have bitter wars involving a group from one section or the other asking a bunch of questions in the other group, and anyone that gets their account suspended goes on to be Yahoo answers martyrs.
There is no real discussion to be gained from the atheists there either as they use anecdotal claims for their arguments. (i.e all religious people are evil because my Catholic father bum raped my asshole when I was a kid). None of them are able to use scientific sources or any evidence to support their claims and expect people to take what they say as literal truth.
Theist: Yes. I believe so. Let me explain why... *goes on to give his argument*
Atheist: God doesn't reel! You're stupid because you believe in sky daddy!!!! We all came from nothing! BIG BANG THEORY IS WRONG! STEADY STATE IS THE TRUTH!!!
This continues all night as the atheist regulars on R&S literally answer as many questions as they can with this shit until they fall to sleep at their desktop in their basements.
