I've already said I'm not interested in blaming atheism for mass murder, just to be clear. But I disagree that the Christianity more easily lends itself to violence than another point of view. I want to know specifically why you believe Christianity promotes the use of force against innocent people.

Leviticus 25:44-46

46 You can will them to your children as inherited property and can make them slaves for life, but you must not rule over your fellow Israelites ruthlessly.
Exodus 21 1-8

21:2 If thou buy an Hebrew servant, six years he shall serve: and in the seventh he shall go out free for nothing.
21:3 If he came in by himself, he shall go out by himself: if he were married, then his wife shall go out with him.
21:4 If his master have given him a wife, and she have born him sons or daughters; the wife and her children shall be her master's, and he shall go out by himself.
21:5 And if the servant shall plainly say, I love my master, my wife, and my children; I will not go out free:
21:6 Then his master shall bring him unto the judges; he shall also bring him to the door, or unto the door post; and his master shall bore his ear through with an aul; and he shall serve him for ever.
21:7 And if a man sell his daughter to be a maidservant, she shall not go out as the menservants do.
21:8 If she please not her master, who hath betrothed her to himself, then shall he let her be redeemed: to sell her unto a strange nation he shall have no power, seeing he hath dealt deceitfully with her
