Actually, NSDAP, "National Socialist German Workers Party". "nazi" is their own nickname for themselves.
The nazis and the commies spent most of the 1920s trying to excommunicate each other from the Socialist International over whose socialism was most pure. But when it came to racial policy, the nazis freely admitted they got their ideas from the American racists/eugenicists of the 20s and 30s. The direct descendants of those groups exist to this day, receiving our tax dollars as respectable "family planning" and "population" groups.
Yep, but try to convince any of those ‘population planners’ of that, and you’ll make their heads explode.
