Well, at the time there were several editorials in the Times of India and many commission reports that document how Hindu mobs went on the rampage butchering the Sikhs. Of course, like our own Rodney King riots, one can evaluate and review the causes that led to this but that does not detract from the core issue of religiously targeted slaughtering of Hindus against the Sikhs.
Perhaps — however you said that the riots at the Golden Temple were due to some kind of temple of hindus built there — that is wrong.
