The left and free speech, redux, redux, redux

Jonathan Chait has written another piece for NY Magazine on the left and free speech. I expect the reaction will be the same as that of his last foray into the speech wars (mumble mumble privileged white guy mumble mumble maybe he has a point). The problem, I think, with the left and its critics -- and he touches on this -- is constructing this as a "free speech" issue when it's not in the legal sense, and that can be used to disprove any argument that says "the left is destroying free speech." It's more overcorrection and a lot of empty signaling.
