New Atheists Richard Dawkins marshals his arguments against believing in God by using His Old Testament command to kill the Canaanites:

The Bible story of Joshua’s destruction of Jericho, and the invasion of the Promised Land in general, is morally indistinguishable from Hitler’s invasion of Poland .... The Bible ... it is not the sort of book you should give your children to form their morals .... Joshua’s action was a deed of barbaric genocide.”[1]

Dawkins goes on to call God a moral monster: “What makes my jaw drop is that people today should base their lives on such an appalling role model as Yahweh—and even worse, that they should bossily try to force the same evil monster (whether fact or fiction) on the rest of us.”[2]
