The New Criterion is devoting an entire issue to the new intolerance on university campuses. Herbert Marcuse opens the discussion with an essay on “Why the Left Hates Tolerance.” Here’s his conclusion:
The classical liberal (who is also the contemporary conservative) championed tolerance because it helped maintain a space for civilized disagreement. Many readers will recall hearing sentences like this: “I disagree with you but support your right to voice your opinion.” How quaint that now sounds! The modern social justice warrior abominates disagreement as a form of heresy. Accordingly, he rejects tolerance in favor of enforced, indeed totalitarian, conformity. It is the antithesis of what a liberal-arts education was all about, which is why its installation at the center of our erstwhile liberal-arts institutions makes for such a sad irony.
