Sakyan (Dalits) are not lower caste people. They are avarnas and outcaste. Outsider of the varna and caste system. The fight in India is not between Upper Caste (twice born) and lower Caste (Shudras), but between Caste Hindus (upper and lower) and Sakyans. The real fight is between the Varnas (Touchables) and avarnas (Untouchables).
