It's women's task to practice eugenics by nature. Moids try to bypass this by using violence, resource monopolization, legal limitations and good old guilt tripping because men are not actually necessary in their current numbers. In the past, we had large predators. Today, moids mostly solve the problems created by them in the first place. They are aware of how obsolete they are, hence why they carved themselves a convoluted artificial niche that's not rooted in actual utility.

Women are subjugated because they are a) trapped once they have a child with the moid b) generally unwilling to put their interests first and c) pre-programmed to empathize with males due to birthing male children. Maternal instinct is incredibly difficult to overcome. That's why rape is an effective tool of war, once you force the enemy population to have your children, they'll mostly have no choice but to accept you. Milking the mommy is something every moid instinctively sees as an effective "get this female to do what I want" tool. They never grow out of it.

Sexual socialism is objectively BAD for the species AND moids. If you have a son with an average shitcel, he will have an abusive father who is unwilling to provide. This is what moids want for male children, because they are not programmed for anything beyond ensuring that they can ejaculate in multiple women. Any involvement past that point is simply mate guarding or limited cooperation to ensure that the female stays.
