Despite me understanding that it ought to be misogynistic, I'm not sure it is.
Eg, when I say fucking hell, I'm not thinking of sex.
If you're talking about the intention of the user, I've used the word cunt when I want to convey that somebody is really, really awful. But I don't think I've ever used it towards a woman (however awful).
Strangely, if a woman uses it towards a man, I think the man must be pretty heinous for her to have done it, but if a man uses towards a woman, I can't help thinking it reflects badly on him.
Which could just be some common or garden double standards, but I wonder if I'm just subconsciously seeing how men and women use the word differently.
Either way, I don't think it's misogyny.
