I have served happily as a professor at Yale for most of my adult life, but in my four-plus decades at the mast, I have never seen campuses roiled as they’re roiling today. On the one hand are gleeful activists on the right, taking victory laps over the tragic tumble from grace of Harvard’s president, Claudine Gay. On the other is a campus left that has spent years crafting byzantine and vague rules on hate speech that it suddenly finds turned back on its allies. For those of us who love the academy, these are unhappy times.

The controversy began with criticisms of some universities, Harvard included, for soft-pedaling their responses to the horrific Oct. 7 Hamas attack on Israel, and for then ignoring the overheated rhetoric of many pro-Palestinian protesters on campus. It has since spiraled into a full-bore battle in the never-ending culture wars.

There’s something sad but deeply American about the way that the current crisis stems not from the terror attacks but from a subsequent congressional hearing at which the presidents of Harvard, the University of Pennsylvania and the Massachusetts Institute of Technology gave such cautious responses that it was hard to understand their positions. It was all very embarrassing; and, in its way, very McCarthyist.
