Thirty years ago, conservative graduate students and the (shamefully few) conservative professors willing to pull the binky of tenure out of their mouths tried to warn others about the outrageous behavior of leftists on college campuses. But the hard Left was already in the end zone of their takeover of higher education. Once they finished purging scholars who didn't march in lockstep with them, they turned to attacking students who failed to conform to their ever-more-extremist agenda and demands.
We lost the fight for intellectual freedom in higher education decades ago. It could be said that we didn't even fight very hard for it. Careerist Republicans and conservatives kicked the culture war can down the road until they were the only ones left and the mobs came for them.
Now it is finally becoming apparent that K--12 education is in even worse shape than higher education and has been so for longer. While conservatives focus much of their belated attention on speakers being banned from college campuses, the hard Left continues its 45-year, scorched-earth march through the kindergartens. Teacher-training schools preparing elementary and secondary school teachers are arguably the most leftist institutions in America today, and, again, we haven't even begun to fight for their de-politicization.
