If she'd asked me that question, depending on just how sleep deprived I was, I'd have either walked away or asked her if she was taking the piss. Coz I honestly don't even understand that nonsense question. A newborn is the least culturally constructed of all human beings and its form is the most unadulterated it can be, straight out of the womb, freshly cooked as it were. What does go on in these gender-addled minds?
And that essay someone linked to is astonishing btw. If she was my student, I'd be tempted to mark it "Good effort, please see me next time you're struggling with the reading material."
Asides the other issues with the text (wordy, waffly, imprecise and smug) if you wanted to play TRA bingo, you'd probably get a full house (de Bouvoir, oblique reference to intersex, vagina-fetishism and so on).
What I couldn't figure out is whether she is deliberately misrepresenting the gender critical/radfem analysis of gender or whether she simply doesn't get it. In either case, it leads her to write an essay that keeps coming so close and staying yet so far from the truth. If it was more riveting or rousing, one could call it propaganda, but as it stands it's just an insipid, uninspiring whinge full of lies.
