Neocommander, after reading through a lot of this thread, I've come to the conclusion that it's perhaps the forceful nature of government and the idea of not mixing races that you prefer, rather than the genocide and hate of the Nazies.
Because of this, I highly suggest changing your self-imposed label to something other than neo-Nazi. You're definitely a social conservative, but not truly Nazi. Fascist fits better, hence the reference in your sig.
As for the debate on the term "Aryan," this is a good starting point:
http://en.wikipedia.org/wiki/AryanThe interpretation of the term that the Nazies preferred had implications that the mixing of Semitic people with the Aryans of Europe (generally regarded as non-Jewish white people) threatened the "purity" of the Aryan race.
However, the term Aryan mostly refers academically to people who settled in India and Iran. Technically, you could say that a lot of the first Europeans came from the Central Asia area, so by extension, they have some Aryan heritage. However, the most directly Aryan people that live today are Indian and Iranian.
I always found this rather ironic about the Nazies. They claimed to regard Aryans above everyone else, but in truth, they were supremacists of people who were only distantly Aryan. If they had instead used the term Nordic, then they would have made more sense with regards to terminology....
Of course, they'd still be racist bastards.
