Robert George, multiply-titled Professor at Princeton University, had some thoughts on how to deal with this.

So what should we do? The answer isn’t complicated, but acting on it will take determination and courage. Colleges and universities must return to offering a rigorous liberal arts education that refuses to engage in indoctrination and challenges groupthink. College courses must actively cultivate the virtues of curiosity, open-mindedness, intellectual humility, analytical rigor, and above all, dedication to the pursuit of truth.

He added this:

This might seem like an unattainable ideal, but it isn’t. I’ve seen firsthand that it’s possible. Twenty-five years ago, Princeton University authorized me to establish and direct a program in civic education dedicated to helping young men and women become determined truth seekers, courageous truth speakers, lifelong learners, and responsible citizens.

He succeeded in his small world, and he cited a number of examples at other schools. But these are anecdotes, not a general trend of success. At many of the other schools he touted, antisemitic and terrorist-supporting riots mostly peaceful protests seized buildings and common grounds, vandalized the buildings and generally prevented the sort of free-exchange of ideas George touted. Those destructive disruptions occurred while school managers meekly watched and many of the schools’ professors participated in the disruptions.

No. The only way to achieve George’s ideal, extremely worthy that it is, is to remove from schools those school administrators and professors, whether ideologues or simply too timid to oppose ideology over education. Both kinds are worthless wastes of payroll.

The detritus must be removed before cleanup can begin.
