Men with a grc are still men. You need to explain how a piece of paper magically means they should be treated differently from other men with regard to the safeguarding, privacy, and dignity, that single sex spaces provide for women and girls.
No pro trans group has ever said 'You are only trans if you have a grc'.
I don't agee with your first sentence but whatever. And trans men with a GRC are not counted in the number of transgender men, they are counted as men.
Your frequent dismissal of ''magically'' just says your mind is closed to how data works. This is not a philosophical point it is a purely mathematical one, which if ignored just shows obstinate adherence to misleading analysis.
And this image posted by you (below), shows the game of the old switcheroo being played. In the first sentence, the number of people stated to be transgender people all gain a GRC and become trans people by the time of the second sentence - just like that - as if by magic.
The number of trans people in prison in this country is just 9 of about 90 000. This means a rate of about one prisoner in ten thousand is a trans person with a GRC. This includes trans men and trans women. The ratio is unknown, but the ratio of GRCs issued is pretty much fifty fifty. This means the number of trans women for any or all offences is about one in twenty thousand people. And of these it is not reported that any one of them has a conviction for sex offences against women or children - not one!
So who are the monsters? Is it trans women, or those accusing them of being all predators?
Even Anne Widdecombe disagrees with you!!! She is a former minister for prisons. She states that trans women are an especially vulnerable group and it is wrong to put them into men's prisons. This is the same woman who had who had women shackled to their hospital beds even on maternity wards because on her watch 20 absconded - so she's no softy, and she sure ain't 'woke'.
