Why do those in favour of opening up all female single sex places to males always come out with this butch women nonsense? My non stereotypical looking female friend (I won't describe her as butch because I think that is fucking insulting) has always without fail used female toilets and changing rooms as she is FEMALE and has never, ever had any issues doing so.
Let's think really, really hard here outed why would a man who isn't a TW want to access female spaces? What would make it easier for him to do so? Ah, yes self id, no need for any external or physical changes whatsoever, just utter the magic words if anyone so much as looks surprised.
Remove the boundaries, remove even the most basic and rudimentary levels of safeguarding but still blame women if they are raped or assaulted or excuse the men doing it with the trope of well, men will rape and attack you anyway, suck it up - weapons grade misogyny.
Single sex spaces are not just for safety they are also for privacy, comfort and dignity but of course women are even worthy of that.
