But you still don’t get this.
If someone decides they don’t prefer it, they “ruin it” for everyone else. In other words, if women prefer to pee only with people who look like other women, and a woman like Aniya Wolf uses the women’s room, all the other women have to accept it. Same goes for any other scenario involving preference for sex, or gender, or whatever - if one person prefers something else, their preference (by the presence), overrides that of everyone else’s.
If one person prefers unisex restrooms - and uses the restroom that doesn’t correspond to his gender - then by doing so, he or she turns that restroom into a unisex restroom for everyone else in it, just by using it.
I’m not complaining about this, just pointing out the folly of pretense.
