It’s not the job of an oppresed group to explain over and over why they shouldm’t be oppressed. But, since I am not trans and I have done some reading on the topic and I try to be a decent ally, I can give it a shot

Basically, any “biological” advantage of a trans woman (cause that’s the “problem,” trans men are invisible) would have is erased by hrt. Muscle density, bone density, you name it. Hormones are powerfull stuff

The only thing that hrt won’t change (if started post puberty) is height. So, if you ban trans women you must ban tall cis women too

ps: trans friends, feel free to tear into my comment ♥️

edit: also, there are cis women with high levels of T, eg that boxer in the olympics thae was harassed to hell and back, are you banning them?
