The only thing about atheism is the lack of belief in god. You will find out that being an atheist does not make you foolproof about other stuff. We have extreme right winger conspiracy nutjob atheists around. The good thing is that they can't use the goddidit reply.
Also, arguing with some theists is like playing chess with a pigeon. They will shit all over the board, knock all the pieces out, then fly away claiming victory.
