Caucasians should stop calling themselves Aryan. Aryan is a Sanskrit word meaning 'noble' and as such, it is not of European origin. The Rigvedic tribes in India came up with the term to describe the military and political class of people in their culture. It was also used as an ethnic term in Iran.
Hitler himself rarely used the term Aryan. He usually described his people as 'Nordic' or sometimes 'Germanic'. He only used the term Aryan to describe those who didn't have any Jewish grandparents. It's the neo nazi groups that want to call themselves Aryan.
Even the Swastika isn't of European origin. Its been used in several Indo European cultures but its predominantly used in India as a symbol of prosperity and good will.
Aryan should be used to describe the Indo-Iranian ethnic groups in Afghanistan, Pakistan, India, Bhutan, Bangladesh, Nepal and Sri Lanka rather than Europeans. We came up with it, man. That's not cool. Just call yourself Nordic.
Also, much love to European nationalists.
