The Nazis are hated for what they were right about (Darwinism), not for what they were wrong about. The error of the Nazis is the error of Mencius Moldbug: Hobbesianism.
The error of Hobbes is to assume that people can only cooperate by subjugation to a common leader, which implies any relationship betweens states, nations, peoples and races, is necessarily one of war, near war, and predatory maneuver preparatory to war, a war of each against all.
Thus people and groups that subscribe to Hobbesianism find themselves at war against all, because they expect to find themselves at war against all – but find to their shock and surprise that their non Hobbesian enemies are cooperating just fine to deal with the common enemy and common threat. Thus people and groups that subscribe to Hobbesianism get defeated, and frequently enslaved or wiped out. All those who believe in something morally better than Hobbesianism, however hypocritically or deludedly, gang up on them.
While Hobbes is disastrously wrong, Darwin and Darwinism is correct. As Darwin rightly pointly out, some races are better adapted than other to a life of artifacts, agriculture, clothing, and fire, and others better adapted to running naked through the jungle. Some races are better adapted to an environment largely dominated by humans, and other races better adapted to an environment largely dominated by elephants and lions.
Those races better adapted to the jungle are genetically predisposed to be less intelligent when dealing with the problems of civilized life, though they may be better at reading footprints in the dust, running swiftly, and smelling the scent of game. They are also genetically predisposed to predation, to rape and robbery, as is apparent when we observe both the American ghetto, and the way Africa is governed.
The races of Africa are more diverse than the races of the rest of the world, thus any generalization is not only untrue of some individual Africans, but also untrue of some African races.
those who sold the ancestors of today’s African Americans were probably just as advanced as the purchasers, individually and as a racial group, but for most African races, that is not the way to bet.
And since it is not the way to bet, it follows that the way to bet is, as Darwin tells us:
At some future period, not very distant as measured by centuries, the civilised races of man will almost certainly exterminate, and replace, the savage races throughout the world. At the same time the anthropomorphous apes, as Professor Schaaffhausen has remarked, will no doubt be exterminated. The break between man and his nearest allies will then be wider, for it will intervene between man in a more civilised state, as we may hope, even than the Caucasian, and some ape as low as a baboon, instead of as now between the negro or Australian and the gorilla.
And superior races, to avoid the annihilation that is apt to follow from Hobbesianism, need to be morally superior, as the Nazis were not:
Nor is the difference slight in moral disposition between a barbarian, such as the man described by the old navigator Byron, who dashed his child on the rocks for dropping a basket of sea-urchins, and a Howard or Clarkson; and in intellect, between a savage who uses hardly any abstract terms, and a Newton or Shakespeare. Differences of this kind between the highest men of the highest races and the lowest savages, are connected by the finest gradations. Therefore it is possible that they might pass and be developed into each other.
