Yes Pritish...You are right..it was propagated by Maxmuller to divide and India and weaken its soul....by saying that Indians are not responsible for the Indus civilization, only outsiders could do that...breaking the confidence and pride about thier ancestors... People who would argue against can check in BBC website in religion section..if you still believe that Aryan Invasion theory... whenever you refer south Indians dont assume only Tamilians...there are the double numbered Andhraites, Kannadigas and Malayalees ( Telugu being widely spoken language after Hindi in India..Does anyone know that!!!!) Be aware that Hyderabad and Banglore are multicultured cities..Andhrites and Kannadigas do not have any issues like Tamilians do...Thank God Tirumala shrines are in Andhra...
