In the post Noxious academics, Orcinus points out that there are right-wingnut professors, too, and provides examples:
“…there are a number of right-wing professors who could face similar academic firing squads if the punditocracy chose to raise their cudgels against them.”
He asks the “conservatives”,
So why are they not every bit as eager to expel these radical academics from our midst? Their silence has been longstanding; if anything, you’ll find so-called mainstream conservatives actually defending thinkers like this (see, e.g., the long-running right-wing apologia for Charles Murray’s repulsive theories about race.)
Personally, I think the principles of academic freedom are paramount in all these cases. But then, I’m not a right-winger.
