You are denying caste discrimination and then washing it off as "post truth" world. That's atrocious actually. Caste discrimination is not some kind of narrative building either, these are lived experiences spanning centuries.
I think OP was being curmudgeonly because they saw this as people trying to drag Indians into the existing culture war stuff as a pawn, after basically pretending they don't exist for decades while getting all sorts of mad on behalf of different minorities.
