I think this piece goes half way to understanding the problem, (women should not have to touch male genitalia), but then is too fearful of causing offence to confront the issue properly (women should have to wax male legs).
If you run a business from your home, you should be able to refuse any client on the grounds of personal safety. The Suzy Lamplugh Trust advises lone workers who travel to client's premises:
"Conduct your own risk assessment on the door step before you enter. If you feel at all uncomfortable or unsure, make an excuse and leave. Trust your instincts."
Clearly there would be many reasons for JY to set off alarm bells, but the fairest and clearest solution seems to be for women to be able to say that they don't accept clients with male bodies, as these women did.
Why should they have to allow any male bodied person to enter their homes?
I don't think it will ever be possible to protect either trans rights or women's rights while it's impossible to disagree with the mantra 'trans women are women'.
