Thank you! The line is mine, but it's heavily inspired by "Gender Nihilism" by Alyson Escalate and "The Xenofeminist Manifesto" as well as other feminist works that go against the 'biological destiny' narrative, i.e. The Dialectics of Sex by Shulamith Firestone which is ironically enough sometimes cited by TERFs so YMMV but I don't read the work as justifying their beliefs at all, though I find it disagreeable in other ways.

It is perhaps also worthwhile reading the sort of discourse the above works arose almost in response to: the patriarchal falsification of the biological facts of cis women and suppression of education relating to that which would threaten the patriarchal premise, beautifully illustrated in Evelyn Reed's "Is biology women's destiny?" (Marxist Internet Archive), because the above works are written to suggest that while the above is true, it may be that the better line of thinking is to ultimately reject identity, because it's not the word but the desire to classify people into identities like this that really is ultimately harmful.
