Yeah. Personally, I don't believe in personhood, it seems poorly defined. Actually, there's this game I really like the way it tackles personhood. You play as a robot, and you get to debate philosophy with a computer. The computer probes you on your beliefs, and at one point tries to ad absurdum you into agreeing that frogs are people. I forget exactly what the arguments are, especially since you can choose a few different things to argue. But it's really neat, because you're a robot debating what it means to be a person; who we as a society should extend personhood to. Personally, I said that frogs are people in My first playthrough. And in the sequel, there's this throwaway joke about how the "are frogs people" debate topic has been banned from the online forums. And I think that's great! Evidently, the NPCs really got into the weeds on that one!

So yeah, I think personhood is an iffy construct and I don't personally identify with it. I'm no person. I reject the very system that would grant Me special status for conforming to its notions of political life. So I don't think murder has much to do with personhood.

Oh, and historically, "person" just means a human body. You know, "it's nice to meet you in person." Letters and phone calls don't count, because as minds sending messages over the wire, we're not people. People are human bodies, according to our vestigial linguistics. What a load of bullshit.
