" This is not my view of the matter; it is the Nazi eugenicists’ view of the matter. In the early twentieth century, eugenics and social Darwinism were far more prevalent in America than they were in Germany. Margaret Sanger and her fellow progressive eugenicists didn’t get their ideas for killing off undesirables—or preventing their births—from the Nazis; the Nazis got them from their American counterparts who dominated the field of international eugenics. So there is a two-way traffic between Nazism and the American Left. "
