thou shalt not kill

I used to work in a toy store. It was quite enjoyable. However, I did feel conflicted every time I had to quietly ring up a toy gun, or direct people to the G I Joes. It's disheartening how prevalent violence is in our society. Just last week, I won a promotional yo-yo in a trivia contest at work, and it makes noises that sound like guns and ammo exploding. It seems that every time I turn around, the destruction and death of violence is being lifted up, whether it's coverage of our colonization efforts (let's call them what they are), rage being broadcast nationally on the top-hits radio stations, or simply showing up in unexpected places like a yo-yo.
"Thou shalt not kill" is a very straight forward commandment. It doesn't say "Thou shalt not kill, unless you have a very good reason." It doesn't say "Thou shalt not kill, unless you're a subscriber to Just War Theory." There's no ambiguity about it. And yet, Christian Pacifism is seen as this strange leftist philosophy, relegated to Quakers, Mennonites, and believers on the fringes of the church. It seems pretty clear cut to me.
