Pointing out that you have a penis doesn’t dehumanize you unless you think male bodies are by their nature lesser. I have a penis and acknowledging that fact doesn’t make me any less of a person! It just means that you’re a member of the social group currently waging a war against women. Not your fault or a personal judgment on you.
Anyway, there are absolutely *zero* “cis-only” spaces I defend. Name one space I support that is open to all cis people but no trans people and I’ll eat my hat.
And of course the common denominator is not “intimate partners,” but… wait for it… intimate partners *with penises*, who commit the vast majority of domestic violence. Why do you think that is?
