Ahhhhhh, I didn't know that ! That makes more sense now.
First time I heard about it I was stonned the feck out, thinking "wtf is dis shiet".

It's indeed a very creative way to show the loopholes of "religious thinking", but I think most people very deep into religion would have the impression to listen to chinese language if they heard that theory.

My own "technique" to make religious people doubt is to prove them I can live by the same "moral standards" without following their religions, and then asking if I'd go to "hell" or "heaven". If I'm going to hell it means their god is not smarter than a douchy kid seeking for attention, if I'm going to heaven it makes their religion useless. That's the shortcut but it makes interesting discussion ^^
