Adolph was the strong, charismatic leader that a poverty-stricken nation needed but unfortunately, his methods were extreme and exclusionary. Jews, gays, people with physical afflictions, gypsies, and several other lesser groups were in the "excluded" group. Bad luck for all of them, surely, and incredibly bad luck for 6 million of them.
