This. As an atheist, I was excited to see Religulous. He makes some great points (though most can be found yourself by Googling "atheism") but loses all respect with his condescending attitude in voicing his beliefs. You don't need to be a d**khole in order to prove your point, all it does is make you appear insecure in the belief you're trying to argue for. There are billions of people on earth and each one of us has our own beliefs, that's what makes us great. But what gives him the right to laugh in the face of others because they're a believer of A and he's a believer of B? I'd like to see Religulous again without the "you believe what?! you're stupid!" attitude.
I never noticed him being a "d**khole" in that movie at all and I've seen it quite a few times.
