I’m so glad your feelings towards these women’s stupidity was able to be flipped around!
One thing I will say is that it’s a shame that trans people have to carry the weight of what some bad men have done in the past to be seen as unsafe to be alone with in the bathroom.
The problem here is that these women didn’t see you as another women, they saw you as a man and they felt unsafe at the prospect of what they thought may happen should they encounter a man in a toilet.
It’s not fair on you at all, and those women need educating.
