The Great Lie about what human nature really is has been promoted mainly by internal battles within our societies

For most of human history tribes and nations fought in open conflict with one another, but in modern times, due to immigration and increasing population, conflicts are more often fought inside our cultures, and often deceptively fought.

I have speculated that this may have begun way back with warriors originating religious asceticism as techniques to calm and strengthen warriors for battle, but warrior ascetics then became asceticism as an an end in itself with a specialty priest class.

Then we see ancient Indo-European conflict between warriors and priests leading to splits and migrations, which happened, for example, between ancient India (Hindu priests) and Iran (Zoroastrian warriors). In our time we have ever more internal conflicts within modern societies between different groups, classes, intellectuals, and ethnic groups, often fought secretly.

The Great Lie about what human nature really is has been promoted mainly due to these internal battles within our modern cultures between different groups, classes, intellectuals, and ethnic groups. The Big Media and our educational system is now telling us to deny patriotism, gender and ethnic differences, and other mostly traditional values, and promoting instead cultural Marxism, homosexuality, pornography, promiscuity, universal equality etc. 

These internal conflicts have led to the disorder and degeneration of the West even more than open conflicts have. This is why fascism on the left or right develop supposedly to create social and cultural order by quickly and totally forcing order. But then fascism ends up denying and blocking human nature as much as the degenerate culture did.

I believe the cultural mess we have today strongly suggests that the way out of the mess is to realize and understand, instinctively and rationally, that real human nature leads naturally to the cultural/social expression of regionalism, localism, and an ethnopluralism of ethnostates, protected by some sort of federalism.

Given who we are this appears to be the best way we can optimize the gene expression we inherited from our human ancestors toward being kin-centered, gender defined, heterosexual, marriage-making, ethnocentric, even xenophobic, among other mostly traditional traits, with group-selection as the primary unit of successful selection, followed by individual selection.

Cultures can operate for a time with behavior that goes against this human nature, with such experiments as Marxism, but our cultures are eventually pulled back by the biological and genetic leash of real human nature to cultures that better reflect real human nature, and humans can then work within and adapt to the environments they find themselves living in.
