We are not big fans of the Art Student around here, but it is fair to mention that the NSDAP and CSA have conclusively won the debate about diversity. Now, a history of how modern humans degenerated through admixture:
The Aryan neglected to maintain his own racial stock unmixed and thereby lost the right to live in the paradise which he himself had created. He became submerged in the racial mixture and gradually lost his cultural creativeness, until he finally grew, not only mentally but also physically, more like the aborigines whom he had subjected, rather than his own ancestors.
For some time he could continue to live on the capital of that culture which still remained; but a condition of fossilisation soon set in and he sank into oblivion.
That is how cultures and empires decline and yield their places to new structures.
The adulteration of the blood and racial deterioration conditioned thereby are the only causes that account for the decline of ancient civilisations, for it is never by war that nations are ruined, but by the loss of their powers of resistance, which are exclusively a characteristic of pure racial blood. – Adolf Hitler, Mein Kampf, Chapter XI
This fits with what we see in everyday life. People without excessive mutations are sane and competent; those with mutations have mental health issues and weird physical problems. Trace admixture — the most common form of racial admixture — acts like an injection of high mutation load.
The important conclusion to reach here however is that Hitlerian solutions will not work. Yes, diversity must end and we need mono-ethnic societies, but we also need genetic health, which means getting away from the high-tax structures and overbearing totalitarianism of the NSDAP.
A more sensible society would select wise leaders like kings, remigrate everyone but its unbroken founding ethnic group, and then set up a society that aggressively awards useful behavior — production, creation, maintenance — while ignoring those who Darwin would move on.
We need a thousand years of aggressive breeding for positive traits before the destruction of our civilization through French Revolution style subsidies for the useless is reversed. What we do not need is another crazy warmonger willing to sacrifice his own people for some symbol of racial purity.
