We know, based on stories of conservative speakers being denied the same rights as speakers from the liberal/progressive echo chamber on university campuses, that this sort of thing has become common. There are different rules for those who bow to and agree with the campus power structure - a structure which includes students and faculty - and those who don't.
Yes, I should have posted this a while ago, like when the Detroit Free Press first reported it. But I kept having to do other things, so it languished. Others reported on it though. And the more I read about it, the worse it got. After reading all four of the reports, it seems to me that the original report in the Detroit Free Press was intended to minimize the disruptions caused by the junior fascists at U of M. They didn't debate Charles Murray. They harassed him and disrupted his talk. The anti-intellectual nitwits tried to shout him down. They put themselves in charge as the thought police. I doubt that a single one of them have ever read a single word he's written. Yet, based on the words of others who also wouldn't face him in a debate, decided that nobody had the right to hear what he had to say.
Conservative speakers like Ben Shapiro and Ann Coulter are labeled as "divisive." They are "provocateurs." They engage in "hate speech." This means that they are in disagreement with current campus orthodoxy. And that must NOT be allowed! So they and the student groups who sponsor them are subject to different, more onerous rules. University administrators are all for free speech, or so they tell us - but! There is always a "but" that only applies to people like Shapiro and Coulter and others who are divisive, provocateurs, and promote hate speech. Campus fascists have redefined certain words in order to excuse their own fascism and fear of contrary opinions. It also conveniently let the rioters and disrupters off the hook. It's not their fault. How can they possibly take responsibility for their actions when they were provoked by a provocateur? Curse those Coulters and Shapiros for making peaceful, human rights respecting young adults into masked thugs!
No one who deviates from the orthodoxy can be tolerated.
