tk, The Aryan invasion is a myth. It has been disproved n number of times. Please read reliable literature and dont get brain washed. How can you have more faith in what a bunch of so called leaders say? Both by genetic and anthropology there is no hint of aryan invasion. The white man used this theory to divide and rule and some stupid indians have given into it. Lie by repeated assertion cannot make it the truth. Yes, caste system has brought miseries to so many. but when it was started 1000s of years ago it was to have a well oiled society. Over the years it was manipulated by people. That doesnt make the principle bad. It is like the Govt was created for the benefit of the people but if it goes corrupt as you see in daily life, does it make the principle idea bad? Before bashing Hindu culture and blindly following the Aryan-Dravidian myth, understand the reality. Dont follow blindly and rally behind the leaders who give you stupid ideas.
