The Dysgenic Overhang
My most spicy take is that all the racism in the past against Italians, Slavs, Irish etc is true.
Northwestern Europeans are the best kind of human from the point of view of building civilization; the evidence for this is very solid. It's not just intelligence. It's a whole bundle of mental qualities (IQ, conscientiousness, obedience, creativity, and likely many I don't know about), it's the catholic Church banning cousin marriage so they have less inbreeding too.
The maximally politically incorrect version of HBD is the one that's most true. There really is something like a hierarchy of being with southern white English people and selected other Northern Euros at the very top.
But people on the woke left who say the definition of "white" has changed are also right.
Italian used to be a type of brown. Irish were a form of nonwhite white people. Etc. Slavs were famously a type of "Untermensch". White has an umbra and a much larger penumbra.
This doesn't seem to fit the reality we see now: Most Slavs, Irish people and Southern Euros fit into Western society just fine. There's no "Spanish lives matter" movement. In fact all these groups are actually being discriminated against by the modern anti-white laws. There are a few wrinkles like Albanian mafia pushing drugs and so on, but it's nothing like the fuss over black and colored people.
So are the wokes right that all humans are equal, actually?
No.
What I think has happened is that as society has become more and more capable - like an engine getting more efficient - so it can run on worse and worse people. If you took current British demographics and changed technology back to what it was in 1750, the country would collapse, there would be no industrial revolution, no empire etc. Current Americans given 1700 tech wouldn't colonize the new world. Etc.
The whites (by which I mean the actual Northern Euros) have gotten worse too. Welfare states have created a population of weak, fat lazy and old whites. But that's ok! Modern technology is so good that a productive 10% can just about carry along the remaining 90%.
The implication of this is that we have a dysgenic overhang - if our civilization ever stops progressing and starts backsliding, there's likely no way to recover. Things would have to get very bad for a very long time until all the freeloaders who collected and all their descendants, died out from harsh natural conditions (real winters without heating, famines, wars that end in genocide of the losers, etc).
Things are very precarious.
It would be better for all concerned if we solve the dysgenic overhang the easy way (return to meritocracy, technological singularity, bio-enhancement) rather than the hard way (collapse back to brutal Darwinism).
