"Can you please cite the last time a Hindu, Buddhist, or Christian cited passages as a justification for mass-murder?...I'll give extra bonus points, though, for the links to Hindu..." Goodness, Teach, haven't you read the Bhagavad Gita, that most holy of all Hindu sacred literature? It's one, long narrative poem in which the son of God brings the son of Man to understand why he must slaughter his kinfolk's people.
Not even close, the Gita is directed to a King on the verge of a gigantic battle. And there is no direction to kill in the name of God. Merely an understanding that good men can be on both sides and may die fighting. The key point was not to become emotionally attached to the killing or the cause.
