Suppose a future world where all the world, every country is thoroughly mixed up by today's racial standards. There is no "white" country, no "chinese" country, no "black" country. How do you think race wars would be organized, "Lets kill all the [racist slur] bastards of this country" wait what, there's no easy country to point to, already making race war quite difficult. Or do you like having race wars? Again, I fail to see what exactly is the "loss" or "gain" of a race existing or not? What has it ever given us? It's like religion and nationalism, very little benefits and pure destruction and waste of human life in the balance of history.

I suppose you will then say, you fear your country would become "Muslim" or insert whatever religion you hate. But Muslim is an idea it's not a race. A religion can convert a country without even a single marriage or mixup because it's an idea, so tell me again how do you feel you are safe from a foreign religion just because your "race" is different? And the nice thing is the arabs or whatever race has you wetting your bed will also have had thoroughly had to mix up with the locals by that point, already rendering them "impure". And I have you covered with a great anti-democratic solution for that: forcible state mandated atheism.

If you do believe in anti-democratic system of governance, then I propose we force every person to marry a person of a different race and forcibly make every locality thoroughly mixed up using information theoretic entropy definitions. Why not, why's mine better or worse than your idea of anti-democratic rule?

Why do you feel among all the cultures there, you know which one among them would will out. I see no point in being among my race if it's a communist or fascist country. The race has already failed me then. Hell give me aliens from mars and I'd gladly live among them if they are liberal democratic and capitalistic. To me these three principles are paramount, the identity of the agents executing them is irrelevant.
