There are many, many reasons why we have sex-separated spaces: privacy, dignity, modesty, safety, fairness, peace of mind, personal hygiene, santiation, cleanliness of facilities, lesbian and gay socialising, group bonding, therapeutic efficacy, organizing and campaigning. And probably others that don't come to mind right now. This is generally for the benefit of women, but also for men too on some of these principle…
>There are many, many reasons why we have sex-separated spaces: privacy, dignity, modesty, safety, fairness, peace of mind, personal hygiene, santiation, cleanliness of facilities, lesbian and gay socialising, group bonding, therapeutic efficacy, organizing and campaigning. But that was only half of the equation. Why are these "rights" only relevant for women? How can you define these as a right if other groups do no…

Depends on how well the prison is safeguarding its vulnerable male prisoners. I expect your implication here is that he should be moved to a female prison. That's usually why this question is asked in this sort of discussion. However this would obviously be nonsense, as he is male and therefore his safety is the responsibility of those running the male prison. It has nothing whatsoever to do with the female prison estate.
> I dedicated almost that whole previous post trying to get you to define what a right to "fairness" really means, but you ignored all those questions.
No, sorry but you asked a load of questions irrelevant to the topic. Just to expand on my earlier response: female-only sporting competitions exist for the most part because male performance is such a huge categorical advantage that sex segregation is needed for the competitive advantages amongst women and girls to play out. Allowing a subset of males to compete in women's sport just because they demand to is fundamentally unfair, because of this categorical advantage.
