We should be really glad HH is speaking plainly after a long period of Starmer apparently tacking back to some semblance of reality. Her plain speaking, that can only be borne of absolute confidence that this policy will not scupper the election of a Labour govt, is the only thing we need to bear in mind, because Starmer's pronouncements are just a truncated version of her statement here, which is Labour policy.
Starmer says only that women are "adult females". HH says "adult females are women plus those with a GRC stating women". Ergo, Starmer is deliberately only mentioning the first half of HH definition. We all remember his "99% of women don't have a penis". For all the sound and fury since, this hasn't changed.
HH is a player, and like all politicians she is easy with messaging. But she's also the closest we can see to a cultural elite, one of those on the long march thru the institutions.
Imagine, early in your activist politics and influencing change in the Labour Party, she pushes the PIE line, for this to blow up in her face. A half century later she's on track to be in power to lock down a policy that effectively negates woman as a meaningful category.
It's not called the long march for nothing.
