Nazi appropriationTerms like "race", "breeding", "Aryan" and others Nietzsche used in his later works were very useful for Nazi ideologues who tried to take him in for their political program. The pitiless humiliation and, eventually, destruction of the weak was favoured by national socialism. Also, Nietzsche's comparison between the Tschandalas and Judaism (see below) fitted in with antisemitism.
Though Nietzsche did use the term Übermensch, nowhere in his works he used the contrary Untermensch that in the 20th Century became a notorious concept in the racist Nazi ideology, that was used for races and individuals that it perceived "inferior", like Jews, gypsies and homosexuals. Nietzsche was not a nationalist, explicitly despised the German culture and also called himself an "anti-antisemite".
