If they'd just leave the male and female toilets as segregated-by-sex factories for male and female people, they wouldn't have to worry about excluding any genders. Because segregation by sex is already gender neutral. You can be any gender you like, or none at all but if you're of the sex capable of producing small, module gametes, you're free to use the male toilets. Asymetric blue short-ish hair, they/them/xie/he pronouns, and of the sex that is capable of giving birth? You're still welcome in the female facilities. Right along with every other female person. Inclusive. But, like, actually inclusive, not discriminating by personality or clothing.
