Another thing, what I am worried about is nobody uses the term appropriately. So I would like to briefly describe the present racial structure of Nepal. About 6000 years ago a kind of civilisation developed in Pakistan around Indus river. These people used to speak Sanskrit as their mother tongue and worshipped Sun. They called themselves as Aryans. From Indus the word HINdus to Hindu developed. These people slowly moved towards India. But in India another civilisation existed-A Dravidian civilisation. Dravidians were the indigeneous people of India. They were darker than Aryan. It is believed that there have been the battle between Aryan and Dravidian.But Aryan were technically advanced than Dravidian and easily defeated Dravidian. At that time Ramayan was written describing the victory of Aryan over Dravidian. Ravan might have been the King of Dravidian. YOu can still see that ,most of the hindu god and Godess have the fair skin and devil dark skin. After being defeated by Aryan Drvidian moved towards the south. In the north part Aryan ruled . BUt Aryan could not chase Dravdian further south from Vindyanchal Hill. But in course of time some Aryan gradually entered the Dravidian region . That is why you still see two distinct race in south India. Mostly Darker Skinned people-supposed to be Dravidian, and fair skin people-suppose to be Aryan. BUt in pakistan you see all people fair - because no Dravidians remained there.
