South Park did a brilliant little parody of this very premise last season.
Yeah. I get it, but the one thing that they miss is that atheism is different from religion. Reason prevails at all cost. So, wars and all the negative attributes of human behavior are subject to critical examination. Although, I must admit that sometimes people do not critically examine their which is why I am always befuddled when I meet atheists who are racist, sexist or whatever. It seems to me that they critically examine their religous beliefs but not anything else.
