Racial segregation was about racism. White men and white women still had their own sex based spaces when they weren’t allowing black people to access the same spaces... and black people weren’t advocating for black men to use women’s rooms and vis versa. They wanted to be able to use sex based spaces that everyone else got to use in the way everyone else used them- separated by sex.

There are many different ethnicities/races, they’re all made up of the same two sexes. It’s absurd to have a white bathroom, black bathroom, Latino bathroom, Asian bathroom, Native American bathroom... it’s not absurd to have two spaces, one for each sex that regardless of their race, every human is bound to be one of.

Sex segregation is about safety, privacy, equality sometimes, comfort levels, etc

Honestly it’s weird of you to just stare at women in bathrooms and locker rooms- but it’s not scary (it’s also not like lesbians/bi women generally make a habit of staring at women in bathrooms and locker rooms, some doing it doesn’t mean most of us don’t realize that’s creepy, also worth noting there’s a difference between noticing someone attractive and staring at them). Females are typically less dangerous than males, I may notice a woman staring, I’m not going to be afraid of the harm she may cause. And she is significantly less likely to want or attempt to cause me harm. Basically, if a woman was staring at me, I wouldn’t really care, if they were being weird about it, I would care and I’d have no problem saying something- if a man were staring at me, instant tension, instant thought of getting out and or seeing who else is in the space, and I wouldn’t dare say a word, I’d just remove myself ASAP.

There will always be risk and danger in public life, sex segregation is one of the ways to attempt to lessen that and offer females spaces where we feel safe and can seek refuge if need be, racial segregation was just about skin tone and hatred.

I think it’s odd that people have a problem with women wanting their own spaces, but not with men forcing women to sacrifice their spaces.
