Aryans have nothing to do with Proto-Indo-Europeans. Aryans are specific Indo-European people. They are Iranians and light skinned Indians. There is nothing European about them.
I can see what you are saying, but there is relationship and the Aryans you refer to are descended from Proto-Indo-Europeans.
Not European but Europid. Brahmins and Ksatryias (high caste Hindus) are strongly Europid.
The Irano-Afghan sub-race is also Europid.
I find the use of the word 'Aryan' to be rather crass, given its appropriation by *that person*.
Nevertheless, I feel that it corresponds to something in the soul of the Europid.
