Masculine vs feminine, meritocratic versus inclusive

 I heard a lot of pro and cons regarding ideology of diversity, equity and inclusion, but I noticed that most of proponents for DEI, are women while the most opponents are men.

Maybe it how masculine and feminine society work.

In all tribal societies, the boy becomes a men and joins dangerous activities of men after a trial. It could be to stay one week alone in forest, or hunt an animal, or undergo something painful as circumcision.

The reason is that men hunt and wage warfare and down need a weakling to hold you back. A group marches at the speed of slowest individual.

So men society is more selective, and prizes independence.

Women on the other hand have other issues, during pregnancy they are vulnerable and need help of other people and they tend to create social networks and include many people.

Women society is more inclusive, and priorities reciprocity.

New World was colonised first by men, and this biased cultures to be more masculine, competitive and individualistic. In South America you have machismo, US you don't have paid vacation for the birth of the child as some poorer European countries have 

In more old sedentary societies who have enough food you notice that social networks are wider, and issues of taking care of family and others have more importance.

After the wilderness was tamed the number of women increased  and they shifted the characteristics of society. 

Neither of these views is correct per se.

These views must be applied in the right context 

You can't be inclusive were you have competition, in a sports team. You must select for competent persons.

But you can't refuse support to a weaker person like a child because it has to man up.

If Steven Hawkins would be born on Sparta, he would be killed, and Sparta would have lost a genius 

Inclusion should increase the pool of talents. As Nikola Tesla said "half of the population is not used" he was referring to the women. He was a particular child and without tutelage of his mother he wouldn't have succeded.

In WW2 Germany selected from top down based on theory. 

US included many diverse people, including German Jewish scientist, and they had a bigger pool of talents to select and US made the first atomic bomb.

Also the selection in a democracy is done from bottom up.

Inclusivity and selection work hand in hand.
