Because all the conversation I’ve seen has been against Trans Women going to women’s restrooms. Which is strange to me because, according to the twisted concept of TERFs, Trans men are not men (even though they are), but “women”.
Aren’t they worried about “women” going into men’s bathrooms?
The transness is the big key. They are okay with women in men’s restrooms as long as they are women, but a trans man attempting to use a men’s restroom is a boundary violation - because it’s part of that man’s statement that he is trans.
It’s a deep insecurity - they live in worlds that are set in stone, and recognizing that human variation is infinitely more complicated than the boxes we try to shove people in is terrifying.
