I don't think there was anything strange about their background. If there was it doesn't really change much. They were trying to promulgate a very linear/narrow culture war (culture doesn't work in such a contrived way as they were trying to accomplish) against Europe and failed. Emulating the Romans etc. The whole aryan nordic thing is talked up too much while the real reasons are enigmatic to most people. They are strange looking people for sure and not really the faces that come to mind when you think of noble leaders. But most world leaders are just slimy nasty people in the first place.
