And, if we imagine for a moment that this is actually the case, would you find it acceptable for this state of affairs to continue, sanctioned by "biology"?
There's no need to fix biological preferences between males and females any more than there is between gay and straight people.
The movement for gays rights found itself countering arguments much like the one's you are making. They stressed the fact that there are in fact biological differences that make them gay.
Hence, when you see gay men in greater numbers in fields like architecture, real estate, and fashion, it's pretty hard to deny that biology plays a heavy role in that.
I think it's beyond obvious it plays a similar role in male / female choices, but feminists and you have denied this. I never said all the differences in outcome between the genders is due to biology; but I have maintained it to be relevant factor.
Feminism, and by that I continue to mean 4th generation feminism, tries to argue that biology isn't a factor at all.
Thus, they end up using a very broken tape measure to try to measure the problems of the world.
For instance they see a 77% pay gap, when there is in fact no pay gap.
They see popular video games like the Witcher as highly sexist, objectifying because guys largely play them, and in their mind it should be 50/50. They won't say the same about a Liam Neeson movie, because their mom who also calls herself a "feminist" watches that, and she quite adores Liam….
And this creates monumental pressure to find the villains responsible for all this. So queue some poor researcher who makes a bad wardrobe choice, and lets lay the blame for all these problems on him. Bring the pitchforks!!
