Mr Iyer what are you saying.. You want to become another Hitler or create a Hitler in India. You better read Raghula sangrithyayan the great social thinker who wrote from Volga to Ganges where you can get proof that caste system was created by Dravidas before the aryans entered in India. Dont throw words as you like without knowing the history. And this kind of happenings was inevitable in the History of Humans. Mankind will march forward always. badrinath
