OK, so there was a reform to the Gender Recognition Act on the cards in the UK minus Scotland. The trans-lobby was pushing heavily for self-ID, which is basically the idea that if you say you identify as a woman, for instance, you are for all intents and purposes legally a woman - no hormones or surgery or anything required.
The Equality Act in the UK provides exemptions, for instance, for women-only spaces (women here being human females of any age, not the troony kind), so the reform combined with the EqA would basically mean that any male person self-id'ing as a woman could no longer be kept out of female-only spaces. This is part of what makes this stuff complicated, because it was not the reform per se that was the problem, but rather how it would interact with other pieces of legislation.
Predictably, UK feminists aka the Terven Coven were not pleased by this development, as it would mean a complete removal of the principle of sex-based discrimination exceptions - for instance, no men in women's sport or prisons, etc.
But this agenda is/was being pushed heavily by so-called LGBT organizations like Stonewall, much of the media including the BBC and Guardian, most of the UK Labour party, and many other civil institutions.
There was a public call for comments to the reforms and eventually, that landed on the table of the Women and Equalities Minister, Liz Truss. She's a Conservative, so in general not really given to gender woo from over-educated under-stimulated middle-class idiots.
Anyway, the new guidance for schools on sex and health education came out a few days ago, and it explicitly states, amongst a whole laundry list of other good shit, that gender identity is bollocks (They phrase it nicer).
Obviously, all these orgs and activists are now trying to memory-hole the shit out of their previous approach, saying "we never claimed to be in the wrong body"; "the cissies made that up"; "gender is not the same as sex"; and so forth till the heat death of the universe. In other words, they all agree with what sane people have been saying for years - you can't switch sex. At all.
This is by no means the end, by the way, but it is kind of a big deal, as the UK was on course to become one of the first countries to basically approve every item on the troony wish-list. For more info on that, look up the Yogyakarta Principles.
So, in summation, women got organized and got shit done. Troons get left holding their dicks (or whatever is left of it, anyway), because they dismissed the organizing potential of thousands of middle-aged lefty women and forgot that twitter and reddit is not real life. It's been pretty delicious to observe, actually. They hold women in such low regard that they couldn't even imagine them being a much greater political force than a handful of loud-mouthed fetishists. Who'd have thunk it?
