Pretty much every RPG/action adventure game and some anime were inspired by the west, at least back then. Castles, swords, heroic knights, saving the girl, etc., even the music.
I tend to count the Greeks (and Egyptians) among this, at least certain tribes of Greeks, namely the Spartans (who were proto-Fascist and had a rigid caste system). The general rule was: never breed with the loser/those you conquer, and this was applied to other Europeans mind you.
The thing about mixing is that there is more than one reason it may happen. Usually it happens out of sexual frustration (like the Mestizo and the Mulatto or the Norwegian guy who imports a Thai wife), or out of a fetish, but what about something deeper than all that? Something very deep, above one's base urges? And what about as a symbol of a relationship, kind of like "political marriages" only expanded? Mixing is usually terrible, especially if it's on a grand scale resulting in the loss of distinct peoples, but we have and continue to send emissaries of a sort to others we want to forge relationships with, and a bond between tribes is stronger when there is a bridge between them that is more than merely alliance. Come to think of it, one of the reasons Japan did not attack Russia along with Germany may have to do with this self-interest because a war with Russia wasn't in there best interest, but what if their relationship with the west had been closer, perhaps like it is today? We are more willing to fight together than back then, in part thanks to the "peace" between us and in part thanks to more people speaking the language of one another, but there seems to be a race between who will take Japan's hand: the other Asians or us, and quite frankly, the other Asians will destroy Japan a lot more than we will, and you will notice they are the kind who are encouraged to go to Japan more (and then be Bolshevized to try and make Japan even more lenient to hostile invaders), because most of Japan's foreigners are Chinese and Korean, and they aren't exactly friendly with one another nor do they behave like one another. Korea is heavily westernized and Chinese are heavily mixed with other Asians to the point that they have no creativity, but Japan has been mostly on its own for close to a thousand years, rejected things like liberalism and Christianity (and Islam now), and so on.
The jew uses the mulatto, the modern Arab, and the mestizo who are typically low-tier with some exceptions, but he doesn't seem to use the Asian/Eurasian in his propaganda, not anymore (did back in the 80s and early 90s but now it's all blacks and mystery meat).
Finally, one of the reasons blood is preserved is to retain the memory that is contained in there; the myth, which most people don't actively contemplate anymore thanks to a heavily socialized world. What about continuing this myth? Growing upon it? Isn't that what has been going on, for good and for worse? History is in the blood and sometimes it's detrimental and sometimes it may not be. I don't know what nature has in store or what it is capable of in terms of the destiny of peoples or even their collective will and consciousness, but it appears to me that cultural life is an expression of this will and a lot of their cultural inventions are a mix of ours and theirs. Their country alone seems to have had its own kind of caste, with the upper region having more western-style appearance, perhaps that ancient admixture. Perhaps the old blood is crying to return home because it's beginning to remember, and the shared nostalgia is attracting one another.
