Two stupidities in one sentence. First, it is manifestly not true that every human being has agreed that there is a right not to be killed (unless you're going to tell us that Hitler and Stalin, for example, were really space aliens).
Second, your "arbitrarily" weasel word is a painfully obvious attempt to wriggle out of difficulties (killing in self-defense, execution as punishment for a crime, etc). Sorry, but you don't get to do that -- or, if you do, then you must allow no less latitude to the rights of property, freedom of speech, etc. Since these other rights do not, in fact, require such weaselry to avoid contradiction (but instead require only equal regard for the rights of others), your position in arguing against them collapses.
You're something like a chihuahua, aren't you?

So, you're arguing for arbitrarily killing?

I'm against the death penalty. And apparently you, unlike me, are against self-defense.
Steve, stop trying to defeat my positions and start examining how foolish and stupid some of yours are. Don't make me offer you a burger from the Gunga Diner.
