Not an apples to apples comparison because in your example a black person say could not marry a non-black person (just change low caste for black and higher caste for white or the other way around it still works) in the US when that's not been the case for years and years. Sure, that's true for some families and some people do think like that but on the whole culturally mixed race unions are commonplace -- now try the same with mixed caste folks in India...
