A friend of mine just invited me to a Facebook group called "the snowball effect" (it's an experiment to see if they can get all FB users to be a member of the group). I checked the group page, and found a discussion on the board entitled "Atheists, your logic is flawed!".
The thing is, that (amusing read) is just the start of it - the actual discussion board contains other such gems as "All girls on Facebook are fat" and "Do you know why I'm fucked up?". The mind boggles... These people need answers ;-)
