Last week Mr Sunak said he wanted to rewrite the Equality Act to make it easier for venues to bar trans people from women-only spaces such as changing rooms and lavatories..
He's not going high level with the quite obvious no rapists in women's prisons, and let's look at sport. If he's talking about toilets, he's unequivocal.
This is what, personally, I've been waiting to hear. I'm assuming he means changing the word sex to mean biological sex in the equality act. He has halted the tide. And yes, I expect him to do more. He's doing it incrementally it's true, but he is doing it.
There wouldn't be much point setting that massively specific cat amongst the pigeons, if he wasn't intending to follow it through.
But, he's a politician, and they're all duplicitous.
But the point is, whatever party you support, this should make the opposition understand that it's a significant point in the run-up to the election.
If Keir can't tell that this is now a subject that requires addressing, he's not reading the room. Again.
If he doubles down, it's not just that it's bad for women, it means his powers of comprehension are woeful, or, he is totally captured from inside the party.
I have no doubt the likes of Kemi and Suella have been chipping away inside the tories to get to the point where Sunak actually does something. but it's working.
I've been rather shocked over the vocal determination to erase women, demonstrated by the Labour Party. We are rights hoarding dinosaurs, gender critical women need to be expelled from the party, some women have penises.
We all know that the end result of this ideology is catastrophic for women and girls. It's basically a rapists' charter. And children at primary school must be indoctrinated into accepting it.
So, for me, there are two issues. Firstly the protection of women and girls, but secondly, not fucking understanding what's going on.
Keir can't claim ignorance of the latter, now.
So let's see him step up if he truly does care about the former.
He's got everything to play for.
