> we've collectively decided I think I agree with everything you wrote except what I'm unfairly reading into this phrase: we don't need to and should not irrevocably "decide" once and for all. We might have been quite wrong to ban some poisons even in the situations that applied at the time when we banned them. If we were right to do so, times may have changed and we don't any longer. Even nuclear weapons perhaps, in certain situations. Similar to a previous comment of mine in this thread, of course I don't know from your passing use of that word what you think about this! But I do think that that worldview, that these things are or should be "decided" in a permanent sort of way, is commonplace.
