I think you're missing the point in context - it's this way for everyone and the objection is that (this group of) women have assembled their special victims group because they think either they're the only ones affected or it's somehow manifestly worse that they are. But they're not complaining about the behaviour, but that womyn are being targeted (by the patriarchy rape culture misogyny etc etc).
It does have to be that way because that's what happens when there is competition. Check out Alfie Kohn's "No Contest: The Case Against Competition" if you want to understand why.
