Bastards. I'd love evidence of the pressure they were put under, and what form it took over those few days between the abstention and surrender, to compel their compliance. That should be a matter of public record.
As for 'Self declaration means going through a long and complex process. People don’t go through it just so they can use the women’s toilets' - words fail. Can't these people read? How do people this stupid get into positions of responsibility?
Proposed Self ID - whatever process of signing.
In actual, real, functional situations women are worried about: - no ID required, since challenging people by appearance and demanding identification is othering, demeaning, whole lot of other words.
So practically: No one needs to sign anything. Any man, with any appearance and any intentions whether trans or not, self IDs by walking into a women's facillity' and immediately invokes all the protections thereof. ANY recognisably male individual in the womens facilities MUST be assumed to be trans and protected as such. So until he does something you can actually call the police for (and good luck with that, in my county you might get a call back in 3 or 4 days time and a crime number) your options are let him crack on or leave.
Also practically: when the government and TRA lobby gleefully and joyfully announce self ID in the papers - that any women's facility is now freely available to anyone born male and women can't refuse - what might possibly be the effect of this becoming common knowledge? Hmm? And which biological sex are going to pay the price? And how can anyone be so thick as to not seeing this fucking great juggernaut speeding down towards us?
