Anger and God

The god of the ancient Hebrew texts is certainly sometimes described as an Angry Old Man--and he certainly slaughtered a lot of Canaanites for that hated worldview, polytheism. But I'm not sure the god Jesus agreed with him on that one--it's hard to reconcile with the "turn-the-other-cheek", love thy enemy message. The Koran certainly follows that Hebrew tradition, advocating that the "hatred of injustice" is a virtue, and Mohammad was indeed a model warrior. I have never seen a story of the Buddha, simply an enlightened man, however, getting angry. I may be wrong, just haven't encountered it--even the Zen-influenced samurai does not kill out of anger or hatred.
