JONATHAN CHAIT: There’s Nothing Funny About Political Correctness:

The student protest at the University of Missouri began as a response to a serious problem — outbursts of vile racism on campus — and quickly devolved into an expression of a renewed left-wing hostility to freedom of expression. At the protest on Missouri’s campus yesterday, on a space that is expressly open to free expression, protesters barred journalists from covering the demonstrations. In one scene, protesters surrounded and harassed Tim Tai, a photographer with the student newspaper, chanting, “Hey, hey, ho, ho, journalists have got to go.” The scene is captured on a video here, which rewards close watching until the end, where Melissa Click, a professor of mass media working with the protest movement, calls out, “Help me get this reporter out of here. I need some muscle over here.”

It is possible — and, for many sympathizers on the left, convenient — to dismiss these sorts of incidents as just so much college high jinks. “College students have been saying stupid things since the invention of college students,” argues Daniel Drezner, in a passage that attracted widespread support on the left. It is probably true that a strange and sudden new hypersensitivity among young people has produced a widespread expectation of a right to be protected from offense. It is also undeniably true that outbursts of political correctness disproportionately take place in campus settings. In recent weeks, UCLA, Wesleyan, and Yale have seen left-wing student activism aimed at shutting down the expression of contrary viewpoints.

Even if it were the case that political correctness was totally confined to campuses, it would not make the phenomenon unimportant. Colleges have disproportionate influence over intellectual life, and political movements centered on campuses can spread well beyond them (anti-Vietnam began as a bunch of wacky kids, too). But to imagine p.c. as simply a thing college kids do relieves us of taking it seriously as a coherent set of beliefs, which it very much is. Political correctness is a system of thought that denies the legitimacy of political pluralism on issues of race and gender. It manifests itself most prominently in campus settings not because it’s a passing phase, like acne, but because the academy is one of the few bastions of American life where the p.c. left can muster the strength to impose its political hegemony upon others. The phenomenon also exists in other nonacademic left-wing communities, many of them virtual ones centered on social media, and its defenders include professional left-wing intellectuals.

It’s not about justice, it’s about power. And the people behind it aren’t good people who are just a little overzealous — they’re awful, horrible people who deserve to be mocked, disputed, and opposed at every step.
