Ubermensch did not have a specific race or ethnicity, but was more about being Eugenic and upholding self-discipline, honour, noble principles & having a strong purpose as well as being considerate of both family and nation. Untermensch did not mean "everyone who is not white" or "everyone who is not German" it is basically what some call a "spiteful mutant." The NSDAP were not secret Neo-Pagans or Atlantis-obsessed Vril-magicians, and if they were that means they did not uphold the honour they proclaimed as a key value in life, and were as deceptive as their enemies.
