Far more important for me are men who identify as men and who treat other women like shit. But actually, I have an issue with anyone who treats anyone like shit. The motives are irrelevant for me - be nice, be kind. It isn’t that difficult.
There's something of a contradiction here, isn't there?
Either you care more about "men who identify as men" treating women like shit, or you care equally about "anyone" who treats others (including, and apparently, especially, women) like shit.
Seemingly, though, you do recognise that there's a problem with males treating females like shit, and that the reason for that is structural inequality - in which case, all female spaces, and the protection of women's sex based rights are important mechanisms to prevent women - in some circumstances, at least - from being treated like shit by males.
If 'women' then includes males, then, as I think you can see, that increases opportunities for males to treat women like shit. As you've said yourself (even though you've also contradicted that statement in your first sentence), it doesn't apparently matter whether that person identifies as a man or a woman: women need protection from being treated like shit for sex based reasons. Therefore, we need sex based protections, safe spaces, etc. So it does in fact matter if those spaces no longer exist.
It gets kind of repetitive, doesn't it? See why it matters, though, @Bunnyfuller?
