Oh my, I can just picture fundamentalist Buddhist monks, shaved heads and orange robes, knocking on my door...

I'm all for polite discussions of varying beliefs though. The only instances I have trouble with keeping it cool are when others aren't polite, or when people insist that religion is scientifically true - i.e., the Earth was created 6,000 years ago, man walked with dinosaurs, Pluto rules my sign, the chakras or chi of accupuncture, aliens built the pyramids...
