It has never been a 'right' for males with TQ+ identities to enter female spaces, it was introduced by males for other males without ever bothering to consult women, and passed through Hansard on the ground of there being so few of them that the impact on women could be brushed off.
It's been pushed until it broke. The good will has gone. It was not women who pushed and broke it.
Yes, it will eventually have to mean that there are female only spaces (re) introduced, in essence what will have to happen is third spaces where there is a mixed sex 'womans space' for anyone of either sex who wants it, and a female only space meaning female at birth and not identifying out of being female so that female people who need female only spaces are not excluded. And yes, this will mean that some male people will have to come to terms with there being female only spaces not open and available to them, and dealing with it.
The only fair solution is that everyone has equality of access and consideration.
The current male chosen solution of 'males do whatever they want and some females get excluded and harmed and that's ok if the males are happy' is just sexist insanity. And it will have to end. And yes, to some male people that will feel like deprivation.
It will still not be up to women to sacrifice the interests of other women to make them happy.
