It's not so much religion that he's lambasting, it's peoples' attitudes towards religion... ie, big dude saying he'll beat you up if you question his religion, or "Senator, This guy's running our country and he believes X. Doesn't that scare you?" "You don't have to pass an IQ test to be in the Senate". That's your answer? Really?
One thing that annoyed me about that preview, and always annoys me, is the "why doesn't he just wipe out evil in the world?" "He will." That skeptic's question has been answered over and over again for hundreds of years since Hume, and asking it again is basically just being a dick. Bill knows that.
Anyway I still want to see this.
