I guess my hangup is that there is one specific gendered insult that is supposed to be far, far worse than any other, even other female-gendered insults, and is unacceptable in any context for very vague reasons of nondescript power dynamics and vague references to “history”. I know about the historical oppression of women, but why this word rather than any other? I don’t get it, I probably never will, I don’t particularly care to, I just find it a little interesting. Also, what about context? You’ve brought it up before. If I live in the UK is it suddenly acceptable? If a UK person moves here are they suddenly “problematic?” Which culture should submit to the other? The UK has a pretty similar history of sexism as the United States does so why is it okay there? I don’t like language policing.
I don’t know why it’s that way either but the fact is it’s not up to us. And I don’t think it’s too hard to adapt to other cultural sensitivities when necessary.
