The author of this book spells out with specificity where Nietzsche diverged from Nazism, especially their violent anti-Semitism, and where they intersected, collectivism, anti-Democracy, etc. The fact that his sister was twisting his work around is not accounted for, and it certainly complicates the thesis. What interests me is that the Nazism that grew out of the misuse of Nietzsche, still lives and is as virulent in leftardist creations such as BLM, Antifa and CRT, such as the belief that life is a zero-sum game, that violence and irrationality are legitimate...
Agreed; the parallels between the progressive left and the Nazi’s is both fascinating and frightening...
