Unblocking the widespread obstruction against real human nature would go a long way toward solving many of the problems of modern philosophy

The alienation and nihilism we have seen complained about by modern philosophers, at least since Hegel and Nietzsche (and especially since the two big World Wars) was largely caused by being unable or unwilling to admit, and affirm, the kin-centered and ethnocentric infrastructure of real human nature, among other traditional traits, like being gender defined, age-graded, heterosexual, marriage-making, and even xenophobic.

Was the obstruction against real human nature the result of ignorance, or a lack of courage. Or is ignorance to a degree a lack of courage?

Why did Hitler punish the Jews for being kin-centered and ethnocentric? The big problem is supremacy and imperialism, not ethnocentrism. The alienation and nihilism complained about by modern philosophers comes mainly from people not being allowed to be kin-centered, ethnocentric, and even nationalistic.

Hitler and the Jews should both have advocated an ethnopluralism of ethnostates and the return to real human nature, while making supremacy and imperialism (and now globalism) the real enemy, not ethnocentrism.
