The thing that is ironic about this all is that "Aryan" comes from the ancient Indians, it is their own self description and there's been no period since written history began that they stopped referring to themselves as "Arya." They are descended from Aryans, they ARE the Aryans. What they should be saying is "None of our ancestors came from outside India, ever." That's what they are really trying to say. Instead, by saying they're not descended from Aryans, its like Greeks saying they're not Ellines.
