I like this story:http://usnews.msnbc.msn.com/_news/2012/04/29/11461385-dueling-in-de...
Nothing says crazy like this story and the crazies that flooded the comment section with posts. As an atheist this story and thread frightened the hell out of me. Mainly because Muslims and Xtians hate atheists equally.
If, after reading this article and the posts, you still believe that atheists can somehow hold a rational argument with any theist over morals and ethics, you have more hope than I do.
Ps. For an extra added bonus you simply must "un" collapse most of the comments.
