Chait is complaining about “political correctness”. Fine, complain away; there are even lines I would draw that partly coincide with the lines he draws. He begins with an anecdote about angry students who littered a conservative columnist’s hallway with defaced copies of a ‘satirical’ column, and threw eggs at his door.
Don’t throw eggs at people’s doors, OK?
There are things you shouldn’t do, like damaging property or sending death threats or harassing people to interfere with their lives in destructive ways. Sometimes people on the left do cross those lines; I’m happy to join Chait in deploring those acts.
But don’t call it “P.C.” That’s a term that raises my hackles straight from the onset: it’s the disparaging phrase used solely against liberals, judging them not by their actions but their purpose. Vandalism and harassment are not ideologically-specific tools, used only by the left; let’s deplore the tactics no matter who employs them, but as soon as you attach the P.C. label, I know right away that you are trying to target liberals only.
