Nordics and Nazis

I was wondering (and I don't mean to offend anyone here as I happen to believe that we are being visited by extraterrestrials.) If perhaps the origin of the "Nordics" in the UFO culture is perhaps unknowingly some Nazi like Aryan perfection ideology among some people.
For example the very fact that we call them Nordics almost implies as much. I mean just because you are from Sweden or Iceland or or have a last name that ends with a "-son" suffix does not mean that you will have blond hair and blue eyes and stand no shorter than 5'10.
I mean if you read and hear of the description of these Nordics they they sound like the Nazi's description of the Aryan Superman. I don't know maybe I am reading into it to much. LOL
