It's less about what you are comfortable with, and more about withdrawing any semblance of choice.
I want to be able to have a woman handle my breasts during a mammogram. Likewise a smear test. I don't want to be called a bigot for insisting.
Female prisons, rape refuges - places which should automatically exclude men. Now they don't. Convicted rapists are being sent to female prisons where they are sexually attacking the incarcerated women.
You might be comfortable with that, I'm not.
Sports, all women shortlists, female psychiatric wards, women only social groups.
Many tranwomen have autogynephelia or, as a transwoman informed us earlier, female embodiment fantasy. Where they become aroused by imagining themselves as a woman. I don't want them enjoying an erection in the Marks & Spencer bra changing room, where my 13-year-old daughter is being fitted for her first bra.
You being fine with it is irrelevant.
