"people like you LOVE getting wound up about women speaking up for themselves."
Yes, you're right. Self-hating woman, that's me. Just adore all women to sit quietly at home, not saying anything, ever. You've seen right through me!
"When people say they are transgender, the vast majority of people assume that means they have had gender reassignment surgery i.e. a trans woman will have a vagina."
If I were the receptionist at the salon, I would have made sure it was all very clear before I took the booking.
"And women should not be put in the position where they have to deal with men's cocks against their will. Of course she was horrified."
That is the salon's fault, for not asking, and not passing on the relevant information.
