Count on BBC to twist everything beyond recognition for propaganda - for example, varnas and castes are two different things. Brahmins(intellectuals), Kshatriyas(warriors), Vaishyas(entrepreneurs) and Shudras(working class) are broader classifications called Varnas and not castes. Any civilization would need those 4 elements to survive and grow. India remains a civilization under seige - under Islamic and British colonial aggression, that has placed native institutions in a hardened and self-defensive postures.
You're kidding right? The BBC loves Indians. And just because India has problems from past invasions - not from the US by the way, doesn't mean we need to import them.
You're pretty generous to surrender your own country and lose your heritage and culture out of white guilt.
