Mr.venkat, it was not only the Hindus but those belonging to other religions also who participated in the Anti-sikh riots and it was basically sponsored by a particular political party. Hinduism has nothing to do with that.
Btw are you old enough to remember the happenings in Punjab and Delhi for about 10 years prior to the anti-sikh riots? One of my friend (A South Indian hindu) who was working for Siemens in Punjab was shot dead by the terrorists. I am not justifying the anti-sikh riots but only emphasizing that it has no religious flavour.
