There are many ways in which people are currently segregated according to ''male'' and ''female'', such as school dormitories, teenage camps, military barracks, prisons, changing rooms, toilet rooms, sporting contests etc ... and most of that segregation is primarily based on the apparent biological sex of the people, rather than their invisible and subjective gender identity.

A lot of feminists in reddit are very supportive of the campaign to change society towards one where gender identity is valued more highly than biological sex; a society where the legal definition of ''woman'' is ''anyone who claims to be a woman'' and anyone can legally register as a woman with no delay and with no questions, and will thereafter be treated as that gender in all situations.

This would create a society in which some males* would have fully functioning female reproductive organs, and some females* would have fully functioning male reproductive organs.

*Legally recognised as males and females, and treated as such in all circumstances.

So what I'm wondering is, in that hypothetical society, how that would look in practice, with regard to the situations where people are currently segregated according to ''male'' and ''female'': would your ideal be to scrap segregation altogether and to treat everyone the same in all circumstances without regard for biological sex or gender identity? Or would you scrap segregation in some circumstances and keep it in others?

If you would keep segregation in any circumstances, what would your reason be?
