This is where TERFs came from btw. “I’m not transphobic, I just want to protect women from predators in women’s spaces!!” It’s the same idea no matter how you try to justify it.
I need people to think for a few extra seconds when they see a political take and figure out whether it is actually a leftist idea or just a facist idea with leftist words. “POC shouldn’t date White people because systemic racism creates an inherent unhealthy power inbalance” has the same outcome as “never mix.” “Uneducated people shouldn’t be allowed to vote, this is why Trump was elected” has the same outcome as literacy tests. If the central message has to do with restricting people’s rights to free speech and bodily autonomy, it’s probably not actually a leftist idea.
