It was a Calvinistic mindset that resulted in millions of American Indians being slaughtered because they were "heathens" by "the elect". Adolf Hitler was actually a big fan of the "Indian Removal" program in America.
When you believe you are an elect people loved by God and that everyone else is inferior and fated to be destroyed by God, it is easy to help God out.
This is Calvinistic thought.
Adolph Hitler borrowed liberally from the American model. Many methods of Hitler’s Final Solution were "inspired by the U.S. government’s subjugation of the American Indian…. He often praised the efficiency of America’s extermination of the [Indians]." Hitler referred to Slavic peoples as "redskins."[31]
Again, racism became a tool of greed. Anyone in Hitler’s way or anyone who had resources he needed was fair game. Nazis were to show no mercy to subhumans, and should "delight in killing and displacing them and stealing their property…"[32]
During the Nuremberg trials, Hitler’s No. 2 man, Hermann Goering, insisted Nazi policy had been identical to U.S policy toward Native Americans.33 But the holocaust in the Americas outdid the Nazis’ Final Solution many times over: "The destruction of the Indians in the Americas was far and away the most massive act of genocide in the history of the world," writes historian David E. Stannard.34 Stannard estimates about 12 million Native Americans died as a result of ethnic cleansing in the U.S. and Canada; 68 to 90 million died in the entire western hemisphere.[35]
