I agree that the trans issue has taken hold as much to do with ingrained misogyny as anything else. (And agree my Westminister joke is really funny
)
But for anyone who hasn't heard (or read it) please do take the time to listen to Selina Todd on the origins of trans activism and how the growth of queer politics enabled this.
I post this link quite often, and usually say it is funny how a socialist feminist academic can say something based on research and be applauded, but when at the time this all started and radical feminists warned about the consequences they were dismissed by lefties who always assume they are on the right side of women.
I think the origins of the theory are on the left, but have been a finanicial opportunity as an area of growth (ie US medical practices).
But I think it took hold because in the end women aren't valued, and in some cases hated, so any arguement that says women rights can be ignored gets a huge amount of support.
Not forgetting that if you say sex isn't real then there cant be sexism, so men as a sex class cant be said to be oppressing women as a sex class. Best get out of jail card free for men, whether on the left or the right, is to say the basis on which women are oppressed, ie their sex, is to say sex isn't real. And what happens to women can therefore never ever be said to be the result of men, and their system of oppression, patriarchy.
