The notion that a university should protect all of its students from ideas that some of them find offensive is a repudiation of the legacy of Socrates, who described himself as the “gadfly” of the Athenian people. He thought it was his job to sting, to disturb, to question, and thereby to provoke his fellow Athenians to think through their current beliefs, and change the ones they could not defend.
