Real natural law must be directed to the biological origin of social behavior. Political philosophy is best understood as a branch of biology. Modern political systems have deviated from the biological origin of social behavior. This is also the root cause of the decline of Western civilization.
A rational creature can understand what is good for him and cooperate with biology and biological evolution. Without biology, there is no basis for political or moral judgments. The rational and emotional way to think about politics would be to affirm ethnostatism as natural law.
Natural law, when including the biological origin of social behavior, tells us that society, and the ethnostate, are natural to man. We have a biology determined human nature even if modern man doesn’t think we do. Our real freedom is limited by various determined choices, but we have the flexibility to be mistaken about who we are and what we can do.
If we include what we really are in our cultural schemes and programs we will admit our behavior, intelligence, and personalities are to a large extent heritable. Both liberals and conservative's block or conceal the basic ethnic-centered and xenophobic parts of 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.
