Mr Subbu, No historians who believe in Induz valley civilization being Dravidian will agree to your notion that Brahmi script is Induz script.. If you find Brahmi script i Induz valley sites that means that Induz valleyy civilization is Arya and not Dravidian. Also for me Dravidian means south Indian and NOT a race related to Polynesians as u thinks. Also Aryans means Brahmins,Kshatriyas and Vysyas who wear Yajnopaveet and have Upanayana culture and not Indo European tribe.
