Well at least that's honest. You are admitting that you want existing rights removed from trans people — that you want trans people denied access to public loos, denied the opportunity to try on clothes before they buy. And you want to deny the victims of rape or domestic violence access to support services if they don't fit your criteria (rather than those of the people on the spot who actually provide the service)
No other group makes demands for have something that wasn't rightfully theres in the first place.
Our safe space is needed for privacy, dignity and safety. It may be partly needed by you for that reason too. But it's also because your need for your identity to be validated trumps everyone else else's concerns.
Any other group in history has quite rightly campaigned to be accepted in spaces and in law that were already theirs in the first place.
This must be the only group that says, no, our own space is not good enough. We need your space. It's not enough to be accepted as trans. We have to rewrite and refine EVERYTHING to suit your agenda.
Tough.
Women have FOUGHT for their right to a safe space.
This is OUR space. Too right the default position is on sex segregation and then very careful consideration and justification for any exemptions and NOT the other way round.
