This part is thought-provoking: The reversal(s) that have taken place in the recent years:
"Only if you concretise the invented cis/trans binary and erase the real male/female one can you even pretend to think that the path to a world with “fewer trans people” is mass slaughter.
You have to argue, despite all the evidence that “trans” is an invented category unknown outside modern Western societies, that it is innate, immutable and eternal, while that of “female” is either non-existent or irrelevant.
(To grasp the full outrageousness of this reversal, remember that we actually do have “fewer female people” in the world than we should, because of sex-selective abortion, female infanticide and other horrific forms of woman-hatred. But until recently nobody at all was trans-identified, and in most places that is still the case.)"
I'm not quite sure if I'd call the cis/trans binary entirely invented, but it's certainly true that it is a recent way of looking at these issues, and that it has happened at roughly the same time as the erasure of the female sex.
Another recent reversal is the way the sex caste 'women' was turned into the privileged 'cis' part of the new gender identity class 'women.'
When you think of that it's rather astonishing that many now accept the idea, given that this privilege would then apply to, say, most girls and women in Afghanistan where they clearly are considerably less privileged than any Afghani males who identify as women but stay in the closet.
