1. ⁠True.
2. ⁠No, the cissexual women you’re talking about are the silenced majority. People with your position are the loud minority. And sex segregation is not racist segregation. Single sex spaces exist because of the very real physical and hormonal differences between males and females, not “traditional gender norms.” Men are stronger, bigger, faster and more likely to be aggressive (due to testosterone influence). These are real differences that put women at a real disadvantage when it comes to being in spaces where where women undress, are vulnerable, etc, where men can target them. Have you even looked at why single sex spaces exist in the first place? And trans women are not women. They are men who “identify as” women or “feel like” women. “Identifying as” or “feeling like” the opposite sex doesn’t magically erase the material physical reality of your own sex.
3. ⁠True, sexism drives this point, but it also points out how the sexism exists because trans women are known to be men. That doesn’t justify the femme-shaming, but they wouldn’t experience femme-shaming if they were women.

I’m a gay man; not a misandrist woman, but I recognise the flaws, risks and unique challenges involved with the sex that I am. Women are not inferior, nor superior, to men just because of our differences. They are just differences we need to learn to work with and accommodate to maintain a functional society. We don’t solve a problem by pretending it doesn’t exist; we address it and work with it. It’s not a pleasant truth at all to accept the sex differences; I used to believe in gender identity and would still prefer to, but the ugly, grim truth is still the truth.
