I'm not sure either. I am very good friends with him and he is one of the brightest people I know. And I have four PhD, a Pew Fellow, two Phi Beta Kappa, and two geniuses in my family.
Maybe he is a villain because he he has a low threshold for stupidity and ignorance?
Sometimes he can be insulting to others. Sometimes he is justified in doing so. Other times, maybe not.
Most people like him. That I do know. He is great with kids. My Daughter loves him.
