Nietzsche gets blamed for Nazism and the other depredations of the 20th century. Unjustly, of course, and most people who assign blame this way have never read Nietzsche.
What Nietzsche, very briefly and in part, was attempting to say is that the loss of the traditional cultural infrastructure would lead to a very different situation from the human race, unlike any ever seen before. The trends he foresaw were inevitable outcomes of the shift of the civilizational nous and our collective mentation. In this, he was completely correct. We are still living out what Nietzsche foresaw well over 100 years ago.
But like most messengers, he is blamed for conveying the message.
