According to this Washington Post article there is an increasing marketplace reaction against colleges and universities that have boiled over with political correctness and leftist agitprop courses.
Back when I was an undergraduate, there were certainly some profs who held passionately to leftist views, but rarely did they let their opinions dominate courses, as one now finds with increasing regularity.
A question worth pondering is why the change. Has administrative discipline relaxed? My suspicion is that there never was much administrative discipline over faculty members, at least at most of the influential colleges and universities. What has changed, I think, is that more and more profs have figured out that they can use their classrooms for virtually any purpose they want (except to question ideas that “protected minorities” find comforting) and get away with it. Circa 1970, most profs thought “my job is to teach my subject” whereas now many of them think “my job is to act as a change agent and help advance my political worldview.”
If the author of the article is right, parents are beginning to vote with their feet and steer their kids away from schools where the faculty is most out of control.
