"At the base of all these Noble Races one cannot fail to recognise the beast of prey, the splendid BLOND BEAST who roams about lusting after booty and victory; from time to time this hidden base needs to discharge itself".
[Nietzsche, GM I,11]

This continual, recurring and circular struggle between Noble and Base, Master and Slave, has generated Culture itself.

Nietzsche avers that polytheism, with its rich array of gods and goddesses [such as in the Hindu, Teutonic, Norse, Celtic, Greek and Roman pantheons] is one outcome of this struggle;

"The whole history of ethnic fighting, triumphing, reconciling, merging - everything that precedes the final Rank-Ordering of all ethnic elements in every great racial synthesis - is reflected in the genealogical confusion of their gods".
[ib., II, 20]

So here we have the idea of the necessary race-war, and the idea that so-called 'racism' is at the root of all great culture.
By the same token, 'anti-racists' preside over an ever more bland anti-culture, like present day 'democracy': the 'melting pot', where only the pot melts.
