That's a downright meanspirited post Publius...
I'm shocked.
:-O !
Perhaps you should've saved that one for the flame board.
Incidentally, those with the most advanced degrees are usually not hard leftists, but moderate-liberals. And they maintain that position simply to blend in with the liberal bureaucracy at whatever university or institution they wish to maintain favor with. It is those with PHD's in the Humanities, Sociology and the Environmental Sciences that fall off the edge of the leftist world.
Logic and reason are all too often diametrically opposed to liberalism. Liberalism has its basis in emotion - not reality.
Naturally, emotion is very unscientific and leads to gross misjudgments. Logic and reason serve the "masses" better every time.
