Academic institutions are increasingly places which attempt to police language (and consequently thought). It's a nigh-on puritanical drive to molly-coddle the overly sensitive and limit debate. And it's even more frustrating considering the fact that an academic institution is the place where young people should be exploring all viewpoints, not just what has been deemed acceptable by the elite or those in power. Also see: de-platforming.
It's telling that some of these are terms which have been used without issue for far longer than half a century. It's only recently that they've ever been deemed to be "harmful". I don't know, it's almost as if...the same word can have different meanings depending on its context!
You may say that this is optional and just a suggestion, but it's a short path from compiling a list of these terms to real honest-to-goodness compelled speech.
