This comment on MetaFilter sums up my feelings about many of my grad school professors quite well:
Respect for academic achievements is slowly eroding into extinction. Good riddance, I say. I have been working several years at a university known as one of the top in the country for its particular field, and here’s what I found out: it’s meaningless. It is an institutionalized popularity and writing contest. It’s as if these folks who probably suffered from social ineptitude at some point in their lives (or continue to suffer from it) are using their intelligence as a substitution for charisma and basic, decent human behavior. Which is fine for them inside their own circles I suppose. However, I personally have little respect for titles, authority, position and supposed academic credibility. The result of your work may be astounding and important, but that doesn’t make you a good person or a decent human being, and it damn well doesn’t mean that I have to show you any respect until you earn it. If I don’t understand how great your work is, then you get to earn your respect from me by being a good person on a general level.
