Really great article about 'brain sex' on Feminist Current today: Why are Progressives Pushing Victorian Era Ideas of Gender?
It is the very first article of this kind that I've felt comfortable enough to share on social media, because it deals directly and relatively dispassionately with the idea of brain sex and innate gender, and what these assumptions have meant for women through history. It articulates the problem with the resurgence of gender identity ideology so clearly in the context of women's history and feminist struggles, that to choose instead to read it as a critique of trans-identifying individuals (and cry 'transphobia!!' at it), you'd have to be willing to overtly dismiss as unimportant, centuries of women's hard-fought strides toward liberation from the gender prison.
Just in case anyone missed it and wants to take a look.
