I happened to run across this article, this morning.

IF she has been standing up, while urinating, in the women's restroom, I can see the other people's reason for being upset. I probably would be, too. Mind you, I'm not necessarily convinced that that was what she was doing. It is certainly a possibility that someone is lying on that bit of information.
If it is true, however, I would say that she is very new to her transition, and it is likely that she has very little contact, at present, of other trans people, particularly trans women. I hope that she finds some mentors soon, that will help her get herself together, and make her transition a lot smoother.
It has been a long time, in my transition, since I had to face that issue. I do remember a bit about it, though. I hope that she is keeping a journal, about her transition. I was advised to do so, and I think that it helped me a lot, overall.
