Could you quote the part of the manifesto that says so / gave this impression.

I can understand that position and think we can call it a day as i don't feel qualified to argue the size of the effect. It could very well be just 1%, i.e. 49/51.

This does not follow from your argument.
Your argument only supports that the author questions the ability of every women who fails to get a job in the field / that modern role.
If it is proven that biological differences do not significantly impact modern role preference and capability, you and the author agree that representation should be 50/50. He never specifies how much of an influence he believes biological differences to have, just that there could be some.
