This is such a problem in mixed spaces of English-speakers in the left.

Like, it legitimately is just not an issue here. I suspect the difference that brought this about has something to do with second wave feminism succeeding in the UK/Aus/NZ while failing in the US but I have never been able to trace the cultural difference. Here in the UK for example you find men calling themselves the word as a term of endearment to mean something like "bad motherfucker", you'll see this in some gangster movies in particular where some of the most misogynistic people on display will use it in that way.

In mixed spaces with americans though this causes all kinds of community issues because the origin of where a user is from and the cultural context of the usage is not AT ALL obvious in the online setting, and it obviously still causes most americans an immediate negative feeling because the cultural use is so different. We ban it in spaces just for the sake of avoiding the trouble it causes and that it's relatively easy to not use it around americans if it makes them feel bad.

But yeah. Interesting language topic, difficult to discuss and even more difficult to analyse, I would really like to read more theories on how the usage difference and perception of the word diverged so much.
