> One can defend oneself and others in a myriad of ways that do not involve murder.

As we used to say in the military, "the enemy gets a vote, too". You may find that your non-lethal methods of self defense come up short when the enemy is equipped with a knife or gun. Or at the state level, perhaps a ballistic missile. There have been plenty of victims of those in the media recently. What non-lethal methods would you recommend they use to protect themselves?

If you want your society (and by extension your belief system) to survive, there must be a segment of that society that is at least willing to engage in lethal violence, if only as a last resort. You do not get to hide behind others who are willing to do your moral dirty work and declare yourself morally superior to them. That's like a meat eater looking down on slaughterhouse workers because he bought his meat at the store (I say this as a meat eater myself).

My society neither shares my belief system, nor uses violence as a last resort.
