But I also know a trans woman who is over 6 feet tall and has a beard. She is considering hormone replacement therapy but has not committed yet.

I cannot help but have some empathy for women -- who might have very good reason to be fearful of men -- who are uncomfortable having this person in female-safe spaces. That is 100% independent of the intentions or actual danger posed by this trans woman I know, which is as close to zero as I can imagine.
