feminism that centres on reproductive capability
Twaddle. If you wanted to be accurate, you could perhaps say gc feminism centres on chromosomal sex, I suppose? It's certainly not reproductive capability, that's a (wilfully?) skewed idea and I'm not quite sure how the writer managed to derive it.
being men or women, masculine or feminine gather meaning, relationally and unequally, largely from each other
Eh? How so? Does she mean, like, feminine hair is longer than masculine hair?
Anyway, some of this actually looks interesting and I'd like to read it carefully, only I've got childcare to do on top of workingfrom home, so no time.
