I am from Eastern Europe myself and there is literally nothing in our history to be thankful about socialism we had in the second part of 20th century. The whole idea of being thankful about getting your country destroyed by communists is cringy and reeks of Stockholm syndrome. "Physically and mentally stronger men", pffff, please. Sadly more like brainwashed fools who still parrot cosmopolitan and internationalist dogma today without even realising it. Communists maybe failed to convert everybody to Marxism, but their dogmas of internationalism, racial equality and other such things infected far too many people.
I think that Socialism could work... if it is not total and not internationalist - so NatSoc. Because if it is total, then people lose any incentive to actually put some effort into anything, because why should you? You need to give some growing space and some property to the people, small businesses etc. Same with internationalism - if you are robbed of your ethnic identity and your sense of belonging to your own people, then the last shred of incentive disappears. If I would live in system, where you have no ethnic group for which to strive and you cannot get any rewards yourself, I would not bother and I would try to sponge off the system as much as possible. I would not give a rats ass about some internationalist ideals and some utopian bullshit of rootless globalists... Which, by the way, is what everyone in the Warsaw Pact did and which is number one reason the system broke down.
That said, I agree with Carpat Avars that tribalist mindset from the ancient world is the best we could get today. That does not mean living in the caves and forgetting technology. That means putting your own group first, then the related groups, then their related groups and then all the others. Identity by blood (and blood only) is the strongest kind of indentity. Indeed, most problems of Europe started with Christianity - a cosmopolitan, globalist, protocommunist, semitic creed, which destroyed much of the tribal identity of our forefathers. It is about time to take it back.
You have slayed me, dear sir. I grovel upon the mere sight of your superior intellect and analysis. I repent, yes, I repent in the almighty Holy Name of Ayn Rand with Donald Trump in the sky with dollar signs, In God We Trust All Others Pay Cash, Amen! Cash in my Social Security, eliminate my Medicare...hey wait, those are Socialist ideas...oh nooooooooo...
Racism is completely necessary, and I will explain why. For a nation to work, you must put your own before the rest. An Ethnostate is ideal, because the less religion and culture go against each-other, the more stable it will be. The natives of your nation should be priority over those who may have immigrated (which I disagree with in the first place) or the few who have succumbed to the sick and twisted ideals of Marxism because otherwise it will lead to a situation similar to America, South America, or the rapidly decreasing stability of Western Europe. Notice how the less diverse they were, the more stable they were? Notice how when less people were infected with the cognitohazard known as Communism, they were more stable?
