Save the caste system. Stop forcing alien systems on hindus. Hindus have survived for long the onslaught of foreigners. India was progressingly peaceful in past, including religions of various denominations along with casteism. The brahmins, kshatriyas, vaishyas, shudras, chandalas, all knew their places and the work they need to do. Order was maintainted. This is what is required instead of the chaos of today. Accept it or not, the most anti-caste supporter to practice it in day to day affairs.
