People (inevitably white far right males) who argue that Hitler was a socialist because he was in a party called the NSDAP (Nationalsocialist [all one word in German] German Workers' Party) singularly fail to forget that history shows Hitler was socialist in no respect whatsoever.
In any case, the party name doesn't make the claim Nazis were socialist but "nationalsocialist".
And first people the Nazis went after when they seized power were... the socialists and communists!
