I agree, I wasn't disputing that there were real people who self-identified with the term, I was contesting your correction that "Aryan" solely refers to these people. You might counter that the overloaded meaning is invalid for whatever reason, but (1) meanings of the propriety of words are boring and subjective and (2) I'm only saying there exists an overloaded meaning, not that everyone will find it valid nor that it excludes the validity of other meanings.

As an aside, I recently discovered (from my new Iranian neighbors) that the term "Aryan" is cognate with "Iran" the country. "Iran" in Persian means something like "Land of the Aryans", and that in 1935 the government of Iran asked its diplomatic partners to refer to it as Iran instead of Persia because of the popularity of Aryan racial ideologies.
