Dude, if you look carefully enough you could find stuff in the bible that's WORSE!
Deuteronomy 7:1-2: "... the seven nations greater and mightier than thou; And when the LORD thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them."
Joshua 6:21: "And they utterly destroyed all that was in the city, both man and woman, young and old, and ox, and sheep, and ass, with the edge of the sword.
Joshua 10:40-41: "So Joshua smote all the country of the hills, and of the south, and of the vale, and of the springs, and all their kings: he left none remaining, but utterly destroyed all that breathed, as the LORD God of Israel commanded. And Joshua smote them from Kadesh-barnea even unto Gaza, and all the country of Goshen, even unto Gibeon."
Numbers 31:1-18: "...And they warred against the Midianites, as the Lord commanded moses, and they slew all the [adult] males. And the children of Israel took all the women of Midian captives, and their little ones...And they brought the captives, and the prey, and the spoil, unto Moses...And Moses was angry with the officers of the host And Moses said unto them, Have ye saved all the women alive? Behold, these caused the children of Israel, through the counsel of Ba'laam, to commit trespass against the Lord in the matter of Peor, and there was a plague among the congregation of the Lord. Now therefore kill every male among the little ones, and kill every woman that hath known man by lying with him. But all the female children, that have not known a man by lying with him, keep alive for yourselves."
It's not just one group of people, one religion, one society that does damage, it's some of the whole... remember that...
