We have single sex spaces partly because we know that there are women like Karen out there, trying to live their lives. They need the scaffolding of women only facilities more than anyone and they should not have to out themselves to make a nhs trust listen to them.
My adult daughters are adopted and incredibly hypervigilant and anxious in public. One of them basically doesn't use public toilets unless absolutely necessary. Tras accuse us of "weaponising" her trauma and go on about the alleged risks that trans women will suffer if they go into the gents.
But there's a trans woman on X who takes pics of herself standing next to urinals - says there's never been a problem, agrees it's unreasonable to use the ladies.
Tras don't listen. It's all about what they want.
