I've heard similar arguments being made about teaching CRT in school. Are you really saying ABCDs are so confused about their own identity that they'll cling on to n antiquated notion of a social hierarchy based on knowledge of the Vedas?
It seems like that could in fact an issue with race-centric DEI training, at least per the one study I found at short notice[0]. But that needs to be weighed against the potential benefits and the fact that race relations are a significant issue across America society regardless of whether we address it explicitly or not.
With caste discrimination, the issue currently exists within a very small slice of American society (immigrants born in India). So even a small negative effect across the rest of American society would wipe out even the most significant improvements in that slice.
