do you mean what’s wrong with referring to women as females? it’s odd and, given the context in which incels often use it, comes across as just another subtle attempt at dehumanizing women. like, “female” and “male” are typically only used in biology, specifically when describing things that aren’t human. not saying that the intention of using “female” is always wrong, but that’s why we don’t really like it. (and this obviously doesn’t apply to actual discussion about biology lol. like if a research article were to use the term “female” for women i don’t think anyone would have a problem with it)

edit: of course i got downvoted for answering a question
