I'm posting this not because I'm suggesting that we need to make counter-arguments in this place but because sometimes it's very hard to understand TRA positioning. This (sort-of) makes an interesting read. Anyway. It's from comments on you-know-where:
Women should not be made to use men's toilets just because they were born with a trans body.
People pretending that women who were born trans are somehow an invasion of privacy of women born cis are just dressing up their bigotry as something else.
So instead of male and female bodies, we need to get to grips with the ideas of cis bodies and trans bodies. And instead of women, and men who want to be women, we have women who were born cis and women who were born trans.
Just FYI.
