God is documented as being rather keen on genocidal smiting. That is part of the exact problem. I googled two relevant examples:

  1: God commands King Saul: attack the Amalekites and totally destroy all that belongs to them. Do not spare them; put to death men and women, children and infants

  2: When the Israelites entered the Promised Land, they were often commanded to carry out total destruction against the Canaanite nations. "they utterly destroyed all that was in the city, both man and woman, young and old, and ox, and sheep, and ass"

I'm not into religion, but it has had a massive influence on my culture (NZ) so I pay some attention to it.
