Do you believe that segregated services — sports, bathrooms, locker rooms, etc — were intended to be segregated by gender, as opposed to sex?

No, “emo” is a social category that is not exclusive with genders, its in a different bucket.

But, yes, the distinction of social categories into groups like “gender”, “race”, etc., is, like the categories themselves, fundamentally an arbitrary social construct.

Binary “sex” is just ascribed gender on the basis of a subset of sex traits. To the extent there is a valid basis for segregating services, it varies from service to service. Similarly, the motivations vary from service to service (and, generally differ from the legitimate justifications, if any.)
