If conservatives want to establish long lasting and stable society's they will have eventually face these truths about human nature

Conservative's leave out or de-emphasize the most important part of human nature and social life: the inborn genetic preference for ethnic group or group selection. This lack of emphasis seems to stem from the activities of nonwhite and minority ethnic groups who adamantly oppose and fear being excluded, and also stem from past failed brutal attempts to establish ethnostates. This keeps conservatives in fear of being able to establish the long lasting and stable society's they rightly want.

Groups with related genes, like ethnic groups, have numerous reasons for cooperating more successfully and harmoniously than with other ethnic groups. Ethnocentric groups are more likely to win the battle of group selection. Real human nature is ethnocentric, not with one group overall superior or inferior but with different talents, never equal, because for many thousands of years right up to our present time group selection, or ethnic altruism, was the best way to be successful in survival and reproduction. So human nature became genetically kin-centered and ethnic-centered, even xenophobic, as well as being genetically gender defined, age-graded, heterosexual, marriage-making, hierarchical, and religious-making, with group-selection and ethnic selection as the primary unit of successful selection, followed by individual selection.

If conservatives want to establish long lasting and stable society's they will have to eventually face these truths about human nature. If real kin and ethnic-centered human nature was allowed to be what it is, it would naturally lead to ethnostates, and finally, if we are wise, to an ethnopluralism of ethnostates for all groups, black, white, brown, yellow, or red, with each ethnostate protected from marauding imperialists, global businesses, supremacists, Marxists, etc., and defended by a defensive federalism. An ethnopluralism of ethnostates could be established legally in the United States with our constitutional separation of powers and states.

Why human nature became genetically kin-centered and ethnic-centered

We should be primarily conceived not as an individual, and not just as the family, but as a unit of a larger ethnic group---it is this institution that is the basic bonding place of larger social life. The family, which is of course vital, is nevertheless not capable of self preservation without a larger group to help protect the individual and family, and to help bond the social morality of the individual and the family living in society. In the end the essential function is the reproduction and evolution of the human race, beyond the individual or the family.

It is the ongoing evolution of  life and in various group selections on the sacred path of evolution to Godhood that best counter ominous Spenglerian pessimism.

History is

History is primarily the biography great men, as Carlyle said, but they also work with, or lead, or need, bonded ethnic groups to complete the historical biography.
