I’ve read (I think this was on a fairly marginal website, which is why I’m not entirely convinced) that there are networks of high-caste Indians/Hindus in SV who promote each other. Looking at social media, I know discussing caste is quite taboo. People who celebrate their caste openly are mocked. Is caste dead, or has it been driven underground? Does it still play a role in places like SV?
