I was chatting with a colleague about this. She's a great woman - really clever, energetic, caring and practical. We were talking about Jack Munroe, and my colleague was making much of the fact that Jack doesn't identify with male or female. I recognized the middle class enthusiasm for newly discovered wokeness immediately.
I asked, "What do you think means that a gamine young woman, with a female partner, who has had a child and faced poverty, isn't a woman in exactly the same way you are? What makes you a woman, and Jack 'non gender specific'?"
My colleague is a strong woman, and has a strong social conscience, and it didn't take an awful lot of thinking for her to realize that in her eagerness to be right on, she was basically suggesting she was a woman in a way a young lesbian mother wasn't, and that was a pretty shitty conclusion to come to. To her credit, she rethought her conclusions.
But this is where 'lady brain' gets us. Women end up rejecting their own selves and other women are complicit in their own oppression and the oppression of the women who reject the label of woman because they haven't got these mythical 'lady brains'. Talk about divide and conquer...
