I don't know about that, this seems right on par with biblical teachings. The God of the Old Testament arbitrarily commanded genocide against innocent men, women, and children justified only by eradicating "moral wickedness." You can argue that the birth of Jesus brought a new era of peace and that the God of the Old Testament operated differently than the God of the New Testament but it doesn't change the fact that the Bible is full of religious sanctioned violence and most Christians see nothing wrong with that.
