i went to a group setting, not therapy, and it was good. just iin the end someone called out that a certain someone there shouldn’t be allowed to use the bathroom. i of course thought they meant i am dirty or something so i got up and left.
i was proud of myself for walking out instead of sticking around for a possible attack or something.
I once read of workplaces that didn’t want transgenders to use the bathroom because personnel was afraid of illnesses. It’s not rooted in science and I hate that mentality. Maybe you could have called it out, but I understand you. I would probably also just leave.
