There is a clear difference between not calling your coworker a slur, which is about prejudice or hatred, and not saying words like 'grooming', which is about whether the least reasonable person you know could plausibly find a negative usage of the word and claim it "traumatized" them to hear.

"Don't use words that dehumanize people" and "don't use words that have some negative connotation, somewhere out there" are meaningfully different systems, and I don't want to work with people tedious enough to adopt the latter. I don't want them to set the corporate or academic culture of our society.
