one who had a GRC and therefor had access to women's spaces and services and called himself a lesbian,
Pre the Supreme Court ruling "women's space" applied the SSE clause that specifically says no trans woman (GRC legal woman) are allowed to be part of it, so not sure that this quote can be qutie right.
Admittedly groups such as RC Scotland tried to claim it was legal to include them, but it never was if they were saying it was a single sex service. And of course Scottish authorities failed to hold them to account for lying..
Admittedly I saw an article where Sex Matters made some bizarre statement like this one, so it seems to have grown as a "fact".
The majority of women services providers knew and know that there is a clause that specifically allows the exclusion of trans women from single sex spaces. And with the ruling if they are providing single sex services this now automaticallly means biological sex.
Which is why the only people directly impacted by the Supreme Court ruling are those with TW with a GRC.
Because their status as "legal Women" has been invalidated by the Surpeme Court ruling.
And much as I loved the story that it was the lesbians "wot won it" ie even a male judge can imagine that if you are a lesbian you aren't going to interested in a penis person, the ruling was actually that the protected characteristic of sex was being impinged on by another protected characteristic. And no other protected characteristic had this insult of being downgraded to a second class status.
The ruling was that the application of the GRA / GRC to the protected characteristic of sex, was in fact discriminatory.
Which we all knew, of course, and is why the EHRC prior to the ruling recommend to the Labour Government (who have buried it somewhere) that the GRA / GRC should be disapplied to the EA.
But then this is hardly surprising as the whole concept of "legal women" was created by the Labour Party who had not qualms about relegating the protected characteristic of sex to a second class status as an act of social engineering. Intending that in time it self indentifcation would be all that was necessary.
