>If you were creating a new system, would you include a clause that says: just in case I'm getting this wrong, let's make sure it's an unalienable right for people to have weapons in case they need to kill me?

I didn't grow up in the US, but being exposed to US political discourse, I always took for granted this right wing talking point (though I thought it was ridiculous from the outset). Thank you for providing clarity and a decent looking source on something that, as you point out, makes no sense once you think a little longer about it.
