Slow down here, guys. Bear in mind the "so he claimed" part.
Granted Jim Crow laws & extermination of Native culture provided Goebbels & the German propaganda machine with much fertile material especially in response to Allied leaders' warnings that Germany would face repercussions for its treatment of Jews, Romani, etc. The charge of hypocrisy was well made.
But I'd be very careful in taking Hitler, Goebbels et. al. at their word. Europe, unfortunately, provided many previous examples of political & social discrimination. Witness Russia after the assassination of Alexander II in 1881.
