I wouldn't take anything a Phil prof says in an intro class too seriously.
Dollars to doghnuts he's overstating things ironically in order to get you to think. Good phil profs don't teach, they instigate.
Remember, they are all students of Socrates. Who was a patronizing, lying, supercilious bastard.
This could be a method of pointing out the fact that Marxism's basic arguments are almost impossible to refute. It doesn't mean he'd actually rather have Stalin as pres to Roosevelt. Marx's use of the dielectic, matched with his view of personal alienation, and thus leading to class conflict are very difficult to refute. You have to get seriously Metaphysical to tangle with that stuff, and even then you'll often end in a draw.
He's probably a leftie, and enjoys being paid to bash Bush a bit, but there's usually more to Phil profs than meets the eye. At least, in my experience.
Edit:
For example, I once had a phil prof spend 30 mins bitching about the ending of "The Panic Room," before I realized he was using his hatred of the ending of a mediocre movie to illustrate Ronald Dworkin's constructivist theories of jurisprudence.
