It's all so bonkers, isn't it?
It is bonkers. And this is what happens. You end up analysing a single point down the rabbit hole. When really the issues are very simple.
For me, now, the main issue is no means no. And if I have to justify no to suit you, then you are already violating my boundaries.
In terms of the differences in male and female brains. This ideology makes women keen to find no single difference between men and women, apart from biology.
Whilst we all know that there are hormonal differences. And then we get involved in how the hormonal differences dictate behaviour.
But still, none of it is innate across the board. You get some men with low testosterone, some women with high testosterone. Some men with high testosterone are very gentle, some aggressive.
So although it's interesting, from a feminist point of view, it's irrelevant from a transgender point of view.
What is innate is biological function. Across the board. Of course with the exception of intersex, which Lees brings up, yet again, to disprove the binary.
