I think the traits you list are a bit too abstract. When people list traits they strive for, they are usually derived from yours.

Yours might factually fit the data, but men don’t aim to be disagreeable, they aim to be independent or confident. Same with women and being empathetic and social.

The problem is that everyone needs all those traits. This is where the author fails by saying the groups are pointless.

I think the ratio of how pronounced the traits are is what makes masculinity and femininity.
