Contrary to popular beliefs, superior races are not characterized by maintaining great civilizations, but rather by ravaging upon other civilizations, so the Romans—who pillaged and plundered other civilizations, who read and borrowed Greek literature and philosophy—would be what I consider a superior race; so are the Anglo-Saxon Americans, who really have no great civilization without borrowing from the French, the British, the Germans, the Russians, and borrowing even their lands from the native Americans.
The superior races are characterized not necessarily by intelligence, but by savagery, by a barbaric psyche that rape, pillage and plunder upon the weaker and more docile, i.e., civilized, races. In terms of intelligence, on the other hand, one would certainly consider the Jews, the Chinese and the Indians as some of the most intelligent races, but they are NOT thereby superior. In fact, they are all quite inferior because exceptional intelligence always implies weakness and effeminacy. The superior races are always more masculine, more psychical, and more brutal.
Another sign of superior races: rarity. Just like the noble mountain lions who are few in number, so the superior races always have smaller populations. The Japanese, the Manchus, the Scandinavian Vikings, the Mongolians, and the Teutonic all have this in common.
On the other hand, it is the sign of an inferior race to have a large population: the Chinese, the Indians, the Arabs, the Hispanics.
Make no mistake, insects such as cockroaches and termites have far larger populations and far longer evolutionary longevity than any beast of prey such as lions, cheetahs, wolves, but do you consider a termite superior to a lion?
As the superior races dwindle in number, the more valuable the genes of those superior races will become. Rarity always means greater value and whose lineage is contingent upon superior individuals who are strong, powerful, and dominant.
Race-mixing of superior and inferior races: A new breed of master race that combines the feminine intelligence of the inferior race, and the masculine psyche of the superior race.
