But if you hear some of the stuff he has said in the last few years, namely saying evolution was "encouraged by the devil" and that the big bang is a fairy tail, then you can start to understand where some of the stupid/crazy suggestions come from. No one I've heard is saying that the guy is generally dumb, as he is universally considered a world class neurosugeon. It's more this compartmentalized intelligence if you will that turns off large segments of the population, while exciting other large segments.
I will admit, when you listen to him speak, the politeness is a nice change of pace. It's just the things he actually says that has me turned off.
