There is no such thing as Aryan and Dravidian tussle and domination and things like that, all these are the figments of imagination of some western bigot who due to domination of Europeans in middle ages got a chance to print his crap. Aryans and Dravidians intermingled with each other and the complex and composite culture of India is because of each of them. Both the cultures have done India proud. Stop creating unnecessary and imaginary struggles and do not attempt to create impediments on the path of success on which India is sprinting.
