Race in Nietzsche's GM

"... 'Gut', i.e., the 'man of godly race' is identical with the name for the nation - originally for the nobility - of the Goths".
[Nietzsche, GM I,5]

The Goths were from Scandinavia, and spread throughout Europe and beyond as a Master Race.
Moving from his theory of the blonds as Nobles, and the darks as Slaves, Nietzsche then posits a pre-history of Master/Slave societies;

"The oldest 'state' made its appearance as a terrible tyranny, as a crushing and ruthless machinery ...
- Some pack of blond beasts of prey, a race of conquerors and Masters, which, organised in a warlike manner and with the power to organise, unhesitatingly lays its terrible paws on a population enormously superior in number perhaps, but still formless, still roaming about ..."
[ib., II, 17]

This is the context of the fabled Blond Beast - the Creator of Culture!

Nietzsche says further;
"The blond beast is at the root of all noble races".
[ib., II,11],

And;
"Europe has for centuries watched the raging of the blond Germanic beast".
[ib.,]

Whereas the "pre-Aryan" population of Germany on which these Blond Beasts threw themselves is;
"The REGRESSION of humankind! These 'tools of culture' are a disgrace to humanity!".
[ib.,]

What could be more clear than that!
