Some of you (not all, of course) seriously need to consider what you would actually say to a person face to face and step away from being keyboard warriors.
I appreciate and respect your personal belief that you are able to view a TW as a woman in all situations.
It is necessary to equally appreciate and respect that not all people hold the same belief as you, or have the luxury of being able to accept mixed sex provisions and all services from someone regardless of their sex.
You're essentially saying here that the need to be kind to a vulnerable male person would preclude women from actually standing up for the needs of a vulnerable female person who needed access to single sex spaces. It would not. I don't intend to be unkind to anyone, but I will not always put a male person's best interests and preferences first, because I believe in equality and that female people matter too. And in situations of single sex female resources being used to prove a political belief around inclusion, I will have been driven to the discourtesy of having to be very plain around the truth. MW has chosen to put female people in that position; it is hardly fair at that point to rely on female people wishing to protect MW's feelings or being too afraid to speak out and so just quietly surrendering their rights. Which means women, such as the woman sharing her experience here, simply having to walk away and a service failing her.
Failing her.
That's not anything MW can be proud of or call inclusive, is it?
