'Indo-Aryans' refer to PERSIANS, as well as Indians, Dravidians, and some Mediterranean groups.
Europeans constitute a separate group, to my knowledge.
Also, Confucianism codified 'clanism' in China as 'filial piety', Japan used in their structured caste system, and India... well India's caste system still echoes to this day. And these were largely patrilineal systems, Net. Think about who wrote entire texts on conquests: Sun Tzu? The Book of Rings?
Again, I have to disagree with you. Blaming imperialism on Europeans is a cop-out. Blaming the application of Industrial Imperialism is som,ething else, entirely.
