"According to Nazis, Homo sapiens had already divided into several races, the Aryan race, had the finest qualities - rationalism, beauty, integrity, diligence. The Aryan race therefore had the potential to turn man into superman. Other races, such as Jews and blacks, were today's Neanderthals, possessing inferior qualities. If allowed to breed, in particular intermarry with Aryans, they would adulterate all human population and doom Homo sapiens to extinction."
