It's not a blind spot. I see women supporting GI.
But I also see that academic "feminism" was captured, just like the government, just like the medical establishment. I've come to think the capture of "feminism" and the immense pressure placed on women to conform to it - which drastically outweighs the social pressure that men experience - was necessary in a part for the predatory industry to become normalized.
And women who support GI are not the main drivers of it. The demand for GI - which is an industry - comes largely from pornography, WPATH, and the APA.
