I think that at the back of this is the desire for absolute certainty. If you are in the intellectual community, living as a Christian means living with doubts and uncertainties. I don't mean worrisome doubts necessarily, but you can't make the people who say you are mistaken go away. "God said it, I believe it, that settles it" is something intellectuals are going to have trouble saying. But Dawkins says he offers near-certainty (which is what someone in science has to say), and that is the closest anyone in the intellectual community is going to get. All the "evidence" is on our side, all the "motives" are on the other side, so that's as close to settling it as anything can be.
Gnus can't imagine in their wildest dreams that they're anti-intellectual. But that is exactly what they are.
