Many things in there, some better, some worse. But the recurring theme of gender identity as being linked to those we parse as same-as-us vs different-from-us, rather than maleness or femaleness as essences definable in themselves, that rings very true to me. Interesting.
Also relevant the misunderstandings of Diamond’s work related, seemingly also by Butler, sadly.
