I'm not sure if you're kidding or not, but if not, the caste system" is a Hindu thing, not an Indian thing. And they got rid of it about the same time Europe got rid of its "caste system", so I really don't know what you're talking about. Perhaps many Hindus believe that their destiny is determined by their family's social standing, etc., but that's their perogative.
I've been to India, and the caste system still exists. I don't know where you're coming from. Yes, great strides have been made, but it still exists. Keep D&D Civil.
