Regarding my answer to an argument of practicality vs morality, I think I have already given an answer in one of my previous posts. In my opinion, we shouldn't apply ethics framework to governments or states, that is, we shouldn't measure them by moral standards, but rather stick to effectiveness or expedience criteria...
without moral standards you have no criteria by which to judge what is and is not effective. should a government protect people from harm? if so than arnt you making the claim that people shouldnt be harmed? if so than why shouldnt people be harmed?
