*Applause for Leolaia*
I like what lowden said there about the Insight book - three million local inhabitants slaughtered by one million Israelites (I believe that's the commonly asserted figure) in one of history's most colossal ethnic migrations, a vast, violent, destructive demographic shift larger even than the horrific flight of ethnic Germans before the Soviet armies in 1945, larger than the enormous movements of people over the borders of India and Pakistan after the 1947 partition, maybe on a par with the great Indo-Aryan migrations of the Bronze Age! Pretty dramatic stuff.
Of course what the Bible doesn't tell you is how Jehovah subsequently tampered with all the archaeological evidence to deliberately make it look like ancient Israel was nothing but a dirt-poor backwater with a population of only a few hundred thousand people, perpetually subject to domination by richer and more populous civilizations in Mittani, Egypt, or Anatolia. Or how he erased all the material evidence for the Exodus and conquest (since none exists now) and then went so far as to plant evidence that directly contravenes the account in his own inspired writings, just to throw us off and test our faith in his divine judgement.
Read Redford and Finklestein. The genocides never happened. They are fiction. It's a moot point - or at least it would be if the insane fundie lunatics of the world didn't insist on applying this falsified "history" to our own time.
