The thing about arguing with Radfems is that ..
… you have to realize that most of them don’t actually consider trans women oppressed. They think we are men, and benefit from male privilege.
They think that we are the oppressor of cis women.
Arguing that marginalized and/or oppressed groups should have their own safe spaces will only cause them to go “But what about FEMALES, we are oppressed, why do we have to let these MEN in?” or something along those lines.
It’s a core disconnect with reality that drives their worldview. Everything wrong with how they treat us stems from this fallacy.
