Wait, owning a gun doesn't give you the right or ability to take a life. Someone trying to kill you gives you the right to take a life, and just being alive gives you the ability. We have thumbs, so it's easy. If someone comes up behind you and taps you on the shoulder and you turn around and blow them away, you're pretty much fucked. You still need a reason.
Guns are just a judicial tool, nothing more. If you aren't willing to protect yourself I can't change your mind, nor do I want to. That's you, and I support that. Personally I'd rather walk out of my house with a gun down the back of my pants than give someone else veto power over my vitality. And that's all it comes down to. Fists, gun, same thing. If I had to I'd use my teeth to protect my family. A gun just makes the defense quicker, and in that situation time is everything.
