Ignoring the massive "if you had good enough plastic surgery to make an apple look just like an orange, then the apple would have turned into an orange" derail, may I just take a moment to celebrate the practical implications of this?
If a group of women, who, due to past trauma find biologically male bodies trigger PTSD, want to set up a rape crisis centre or homeless shelter that is for biological women only, they can. (This of course doesn't for a moment mean all rape crisis centres and homeless shelters have to be so - just that there's space for such a place if a group of volunteers identify an need and set it up).
If it turns out that a particular sport can only be played safely and fairly if it is restricted to biologically female bodied players - then it can be so restricted, legally. Which isn't to say there isn't a place for other forms of sport and other events which can be set up to be more broadly inclusive, again, just that it's lawful to set up proportionate restrictions.
It hopefully means that prison governors and prison psychologists have also been listened to when they point out that any transfers between the male and female prison estate should be looked at carefully, and on a case by case basis with gatekeeping in place, not via a blanket policy of transferring anyone who self-IDs regardless of the risk to other prisoners.
I'm reading this as a quite major win. (Hence the desperate "apples are oranges" attempt at a derail.)
