I would tell the Hindus to face death cheerfully if the Muslims are out to kill them. I would be a real sinner if after being stabbed I wished in my last moment that my son should seek revenge. I must die without rancour. You may turn round and ask whether all Hindus and all Sikhs should die. Yes, I would say. Such martyrdom will not be in vain.
The pacifist, or anyone, who claims, “Violence never solves anything.” Or, “Violence is never the answer” enables the murder or enslavement of themselves and/or their followers. Gandhi was smart enough to realize the principles he adhered necessitated this outcome.
The principles of Gandhi do have application in many situations but not in all. The consequence of not having a viable “Plan B” if non-violence fails in the face of violent oppression is the extinction of your society and perhaps your species. In the long run the pure pacifist guarantees the occupation of their place in history and the elimination of their existence in the future.
