Not always an alien influx followed by racial admixture.
One of Der Movement’s favorite memes is the idea that national decline and the fall of civilizations always have an external racial basis – i.e., the decline and fall occurs as a result of some sort of alien influx followed by “racial admixture.”
A look at history provides many counter-examples. Consider the Italian Renaissance, centered on North-Central Italy, particularly Tuscany-Florence. The great intellectual ferment there changes the world and then essentially vanished, all without the influx/admixture model being relevant. What happened to the great Italian artists like Michelangelo and the all-around figures like Alberti and da Vinci? Where are the great German composers today? After Nietzsche and Heidegger, what happened to German philosophy? What happened to French culture and French martial glory? Where’s the English Dickens and Shakespeare today? Isn’t it true that the Third World influx into Great Britain occurred after, not before, they lost their empire? Spain lost their empire, but that empire was formed after they had thrown off centuries of Arabic rule; it wasn’t that the “Arab influx” was responsible for Spain’s fall. Does anyone really believe Portugal lost their empire because of “an influx of Negro blood?” Was it really possible for a small nation like Portugal could maintain their lead in exploration and colonization after larger European nations got involved? Did “racial admixture” lose the Netherlands most of their overseas possessions? Did the transformation of Scandinavians from Vikings to SJW social democrats involve “racial admixture” or did the alien invasion of that part of Europe occur after the behavioral and cultural changes?
In these cases, to the extent the problem was biological, it was internal – dysgenics including the counter-selective effects of war, Frost’s genetic pacification, and the breeding of the unfit and the botched – as well as cultural/historical (Spengler?). In many cases, alien influx and admixture, when it has occurred, was the consequence, not the cause, of decline. One can speculate that the Ancient World was similar. In some cases of course, admixture may have caused decline (Ancient Egypt? The Middle East?) but that’s as much the exception as it is the rule.
But Der Movement can’t get is head around such ideas, just as their heavy breathing about Paleolithic/Neolithic differences in Europe typically doesn’t understand that such differences were in place long before the beginnings of the Ancient World’s Classical Civilizations.
I would invoke “cognitive dissonance” here, but that implies some sort of cognitive process to begin with.
It’s a bit humorous that the same Alt Right that has disdain for S. Italians also has an obsessive man-crush on Julius Evola who is described thus:
Giulio Cesare Andrea Evola was born in Rome to a minor aristocratic family of Sicilian origins.
Again, I could say “cognitive dissonance” but that implies some degree of cognitive function, and I’m not sure how much of that Der Movement actually has.
