"...start from the specialisation in ruler castes, warrior castes, priest castes and the peasant and artisan people."

I did not start there, and humanity did not either. Where were ruling castes ~500kya? Where were cities, and artisans, and soldiers? I do not think they existed then. Tribes, extended families, existed, and they clearly were competent to make what they needed to survive, even structures of timbers, before our species even existed. These are human capabilities, not institutionally derived, but innate to us, like antlers are to stag.

Also innate to us is a family and tribal hierarchy, as it is to Elk, or cattle in their kinds, who do battle for primacy amongst their herd. But institutions have perverted our many instincts, including our combat, into collective endeavors and removed our mercy from us, prevented us from recognizing we have won and gaining the benefits.

Overlords take those benefits from soldiers, whom they have no concern over killing en masse. The are psychopaths, have no tribe, unlike us. We do not kill naturally, just as other creatures combatting for primacy in their herds do not.

Regarding the tension between the sexes, it is also natural for women to shit test men. These instincts have all been abused by our abusers. It isn't natural to women to destroy men, however, nor for men to subjugate women. We need each other, very blatantly obviously, because we are clearly one species, one humanity. Our instincts are twisted and men rape and demean women, while women also exceed their natural roles (which I will refrain here from discussing because there is no need, nor benefit to either of us from it). The best of women have tested men always to be availed the best of them, for the best for their families, and it is in a changed world these instincts are augmented with indoctrinations and propaganda to emasculate men, and infeminize women as well.

I am impressed most about you that you inherently grasp some sense of the right way to reason with a man, rather than to fall for any of the massive incentives you are given to strike killing blows, with power to do so that is dangling before you, from courts, from platforms, from feminism. That you ground yourself on your gut sense of what is right and then refine it by what your reason tells you is true, is admirable.
