More evidence of ideological intransigence can be found in the “bias response teams” that are now regular features at many universities. One Michigan State student had a bias report filed against him for watching a Ben Shapiro video in a dorm. A faculty member at the University of Nebraska-Lincoln was reported for having a Trump sticker in his office window. Another professor was hit with a bias report after discussing the infamous Janet Jackson “nipplegate” controversy. The offended student said the professor had not couched the discussion with enough moral qualifiers.

These incidents don’t represent the normal campus hysterics to which we’ve become accustomed. A growing and strident sect of campus activism is coming to oppose not merely differing opinions but even talking about differing opinions. This is a new and far more uncompromising brand of progressive politics, where even an unsympathetic and progressive depiction of the Ku Klux Klan is too much to handle.

Administrators are partly to blame. University leaders have been far too quick in recent years to yield ground to political zealots, with the result that zealots feel that they more or less run the show on campus. They aren’t wrong.

But the real responsibility for this mess belongs to the student activists.
