Political Science professors, studying the art of deception and using their degrees to push BS on the people. Experts in economics, foreign affairs, psychology, medicine, law, history (All of human history, not just political), engineering, climate, and bull feces. Should be trusted with your life. Warning, some might be very verbose so proceed with caution.

Of course the fairest and most open minded species are the conservative kind, but hey, the are not threatened by their passion for liberty. The collectivist raise hell and lower your grade if you even question there ideology.
there ideology=their
