I think people who want to cast Nietzsche's name around should understand what they speak of, and not try to polarize him into arguments fabricated from the dumkopf groupthink of our time.
Too true...
However, he did leave us plenty of writing on the importance of heritage, race, and most importantly, breeding upward. He also spoke of how most people are parasites who are unneeded by future civilization. Connect the dots.
Connect the dots?.. He does seems most concerned about the idea of breeding upwards, about the mixing of races, about heritage. But when he uses the word 'race' does he mean to refer to matters of ethnicity or rather overman/underman?
The topic of your post indicates that you think that Nietzsche was a fascist. Fascism as a concept involves, among other things, some sort of nationalism: nationalism as a 'unifying force'. Now Nietzsche did NOT seem to lament the mixing of 'races' per say, at least where it was an internal motivating/agitating force in the resulting individual. (And he was surely not a facist in a politial sense: fascism has always depended upon the masses: didn't he preach seperation from the masses and all ideologies that must stoop to them and involve them?)
"200. The man of an age of dissolution which mixes the races with
one another, who has the inheritance of a diversified descent in
his body--that is to say, contrary, and often not only contrary,
instincts and standards of value, which struggle with one another
and are seldom at peace--such a man of late culture and broken
lights, will, on an average, be a weak man. His fundamental
desire is that the war which is IN HIM should come to an end;
happiness appears to him in the character of a soothing medicine
and mode of thought (for instance, Epicurean or Christian); it is
above all things the happiness of repose, of undisturbedness, of
repletion, of final unity--it is the "Sabbath of Sabbaths," to
use the expression of the holy rhetorician, St. Augustine, who
was himself such a man.--Should, however, the contrariety and
conflict in such natures operate as an ADDITIONAL incentive and
stimulus to life--and if, on the other hand, in addition to their
powerful and irreconcilable instincts, they have also inherited
and indoctrinated into them a proper mastery and subtlety for
carrying on the conflict with themselves (that is to say, the
faculty of self-control and self-deception), there then arise
those marvelously incomprehensible and inexplicable beings, those
enigmatical men, predestined for conquering and circumventing
others, the finest examples of which are Alcibiades and Caesar
(with whom I should like to associate the FIRST of Europeans
according to my taste, the Hohenstaufen, Frederick the Second),
and among artists, perhaps Leonardo da Vinci. They appear
precisely in the same periods when that weaker type, with its
longing for repose, comes to the front; the two types are
complementary to each other, and spring from the same causes." (Beyond good and evil)
Nietzsche seemed to me to be concerned primarily with the overman, where race, if considered in an ethnic sense, is a factor of flexible status on the way to the overman. Overman = someone who has the capacity for drawn out obedience towards a personal goal, who harbours a personal stance on what is good and bad, and who abounds in will on his way to his conception of the good.
