"I have intentionally adjusted my teaching materials as the political winds have shifted. (I also make sure all my remotely offensive or challenging opinions, such as this article, are expressed either anonymously or pseudonymously). Most of my colleagues who still have jobs have done the same. We've seen bad things happen to too many good teachers — adjuncts getting axed because their evaluations dipped below a 3.0, grad students being removed from classes after a single student complaint, and so on.
I once saw an adjunct not get his contract renewed after students complained that he exposed them to "offensive" texts written by Edward Said and Mark Twain. His response, that the texts were meant to be a little upsetting, only fueled the students' ire and sealed his fate. That was enough to get me to comb through my syllabi and cut out anything I could see upsetting a coddled undergrad, texts ranging from Upton Sinclair to Maureen Tkacik — and I wasn't the only one who made adjustments, either."
