@StolenCookie What is the difference between a trans woman and a violent non trans man saying he is trans in order to enter what should be a women only space? How can we tell the difference? How can we let one in and keep the other out? It is possible to have grave and serious concerns about the repercussions of opening female spaces to non females without thinking all trans women are dangerous. It's possible to be distressed and triggered by seeing a penis without said penis being used to commit an assault (indeed it is possible to be triggered by the presence of a male body in what should be a female space without so much as a fleeting glimpse of a knob penis.
By declaring that any man who says he is a woman is welcome in female spaces you are putting out the red carpet for every pervert, psychopath, paedophile and misogynistic murderer * to say 'I feel like a woman' and be given free reign to waltz into women's spaces.
For the avoidance doubt by those who like to triple jump to conclusions I am not suggesting that all trans women fall into any/all of these categories. I am pointing out that if the definition of women we use is 'umm, err it's very tricky, you can't actually define it but if a man says they are one then that's good enough for me' then there is literally nothing to stop any* man declaring that he is in fact a women. How do you propose to stop bad men from exploiting this massive loophole?
