Very few desi people know that "yeah kiss churia ka naam hay" therefore I have not come across an agnostic desi show off yet.
Don't mean to be rude but aren't you showing off here? I happen to know few agnostics and yes there are desis among them. Any body can be a jerk and a showoff be it an atheist or religious person, but I don't agree with your generalization here that desis who denounce their born in religion are showoffs and think that theist people are stupid, in fact this thread shows quite the opposite.
