What does the hindu caste system have to do with islam? Hindus are not islamic. Most of the muslims in India went to West and East Pakistan(Bangledesh) when the countries gained independence. The caste system is not racist, but elitist. Not sure what the first sentence had to do with the rest. The untouchables or Dalits as there now known are repressed due to their lineage. Much like we do in many of the martial arts.
