No, no one in this thread is using that vocabulary. I am, because I think that's what people are describing, and it makes me sick.

I'm not misinterpreting a thing you said. No, I'm looking at exactly the situation you are describing:

I'm in my house. It's 2am. I see a couple of people in my driveway fucking around under my car.

And you're saying that a valid moral decision is to leave my house with the intention to kill someone?

That is seeing a situation that you know you could leave alone, and choosing to introduce lethal force. That is fucking hunting for conflict to a degree that is absolutely frightening.
