*This has been discussed with regard to a public toilet, where also only the women's toilet was changed. Many people here are very angry about it.
It is really revealing, isn't it?
Women's right to privacy is under attack.
It is not about trans people, it is about giving males access to women's spaces. If it were about trans people, they'd change the men's toilet, too.
That said, if you see a man in there, do ask him to leave and complain if he doesn't.
After all, the sign says "all genders", not "all sexes". Gender is a social construct. And there's no problem with female people who identify as trans, non-binary or dinosaur using the women's toilets.*
This. I'm really, really angry about this too.
Ask them why they are leaving the men's toilets as they are. Why don't they convert half of the space in each men's bathroom to accommodate MTT? Or why don't they have a third bathroom? Why are they forcing this on women who need privacy and dignity? Also, the safety issue is important. If biological males are allowed into female spaces there IS a risk that females could be attacked especially as it is known that some men identify as women to gain access to women's spaces and abuse and hurt them.
Many MTT are scared to use the men's toilets because of the threat of male violence against them, usually from strangers. Women in abusive relationships are scared of their partner hitting or raping them. Heterosexual men have been attacked in toilets. It’s pretty rare but it does happen. I always wonder why then, is it not the same when a female says that she has the SAME fear of male bodied violence from a male who is a complete stranger to her in a female space?
Finally, definitely email. It's always a good idea to have a paper trail of these kinds of things. You could also print it out and deliver it to them.
