They are simply rude, vulgar words.

If a lot of people use discriminative or vulgar words intentionally or unintentionally to protest against overcorrection of language and "political correctness", I will be too shocked to say a word. On the other hand, the idea of inclusive, bias-free language is understandable to a certain extent.

I think that the rude words Trump supporters use---bitch, bimbo, blonde, whore, and so on---are not only excluded from the list of 'preferred words'; they are also missing from the list of 'problematic/outdated words'. They are simply rude, vulgar words. They have nothing to do with the matter of political correctness or overcorrection.
