I’m sure this will have been covered before but ...
GC people are happy to support a campaign for third spaces. I know it’s not always practical, cost-effective etc but in principle single-sex spaces for men and women and third spaces would be good. When it comes to toilets in small restaurants, cafes etc full enclosed unisex would work as they do for disabled.
It seems the TRA lobby are more interested in opening up single-sex to people by gender identity. Third spaces would not be inclusive and would be othering.
As the alphabet+ is so inclusive and caring surely they should be campaigning for third spaces to stand with non-binary people. Trans women and TRAs would then be able to us those spaces without outing themselves , they would be boldly standing up (to pee) and showing solidarity with NBs.
I know toilets and changing rooms are a small part of the single-sex spaces but if Jameela Jamal, Emma Watson, the TRAs, all gender fluid, NBs, trans people and all those who support mixed sex spaces or aren’t bothered by the genitals of those peeing next to them use those spaces there will be no problem.
