Please come out of your slave mentality - you have sold your soul to white man and would go to any length to work for money provided by them to you and your family. So stop preaching this gospel of untouchables in Hinduism as told to you by your white masters. Before you talk of Hinduism look around for crimes committed by your white christian masters against your black,latino and asian christian brothers. You would have met same fate from your masters but for Hindus who keep you safe from them in India.
