Those don't exist. The women's locker room at the gym might be the only true safe space.
Edit: Japan and Mexico have “women only” train cars. The women still have to run a gauntlet to make it into and off of those.
No, what I want is a culture where we don’t need “safe spaces” because male aggression, domination, and sexual conquest of women is not central to how masculinity is viewed. The Gerai of Borneo view violence as lazy and there is essentially no such thing as rape. Same for a lot of other cultures. I want that.
