Why does the demand for "equality" rise from the ashes every generation like a zombie firebird?

It probably began way back with the "universalism" of religious "spiritualism" and then moved on from there to political philosophy and culture in general.

It was highly cynical but Nietzsche was on to something when he saw the will to power behind those who advocate equality, which we see in Marxism, feminism, the civil rights movements, and postmodernism, with their demands for equality which are mainly the will to power or will to superiority of one group over the others.

When we clearly see and admit the biological origin of most of social behavior then we may be able to move past the great confidence game and swindle of equality, which only leads to civil disturbances and even civil war, because equality does not harmonize with real human nature.

No matter how often religions, political philosophies, or cultures tell us that we are all the same, the biological origin of most of social behavior has affirmed throughout human history that human nature is kin-centered, gender defined, age-graded, heterosexual, marriage-making, hierarchical, ethnocentric, even xenophobic, and religious-making, among other things, with group-selection as the primary unit of successful selection, followed by individual selection.

When presumptuous and arrogant politicians, feminists, etc. smile down on us condescendingly and tell us that we are all the same and must be equal, rather than telling them that they are dangerous fools seeking power, which they are, we need to tell them that real human nature leads naturally to the political and cultural expression of regionalism, localism, and an ethnopluralism of ethnostates, protected by some sort of federalism. Given who we really are this appears to be the best way we will "all get along."
