No one ever seeks their validation by demanding to be excluded from male spaces, do they? They never get upset because they went into a male space and no one cared, the men in there just saw a gender non-conforming male in there with them and shrugged and got on with their lives. There’s never a news story about a poor trans woman whose identity wasn’t affirmed by being kept out of a male space, it’s always, always about not being able to get into a women’s space and it’s always, always a space where women are vulnerable.
Maybe that’s the role of men. Men’s only spaces should make a deliberate point of saying “Halt there! Who is this fine lady who doth pretend to be a man and enter our space! Thou art clearly a most womanly woman who does not belong in here! We have never seen a more feminine human with such alluring femininity and we are offended that thou thinketh we would be fooled!” Then have them smack them on the arse, wolf whistling as they go and send them on their merry way glowing with affirmation and validation.
Would that be enough, do you think? Or is it possible that getting to see naked ladies is also part of that validation, per chance, for er…reasons?😡
