There is no proof that todays poor Dalits were anyway inferior to other castes in Hinduism. There have been several rulers from today's so called low caste. In fact, Brahmins came into ascendency only during the British because other castes were too proud to play divide and rule game of Britishers. Before that time, rulers were invariably from other castes. I am happy to see distortions in Hindu society brought by gora rule is finally waning.
Compare this to Christian royal family in UK. Queen is always from the upper caste rest are mere serf.
