Everybody should work together to wipe out caste system prevailing in hinduism. This is curse to the society. Hindu religion is the most scientific religion. Some vested group who have dilluted the religion for their own benefit. All are equal. Due to high handedness of a section of upper caste, many hindus have converted to Christianity and Islam. Once converted to other religion, they become angry and anti Hindu. Bangladesh is a an example where 90% muslims were converted from low caste hindus due to atrocities from Brahmins. In North east India people have been converted to Christainity and the process is still on. The caste system should be stopped. Otherwise Hindu religion will vanish from the world.
