Re: realism. Some outrage is a nice way to temper realism with civility. If we temper it instead with only a pragmatic calculus or some Randian or Social Darwinism there's a chance we can delude ourselves into a fascism, jingoism or militarism. I prefer to play tit-for-tat - lead with the pillow, reply to sticks with hammers. But if in pursuit of the pragmatic we abandon the ideals, we're going to optimize the 'wrong' objective. In other words - the outrage is a way to call for the US to recognize inalienable rights (which mean that no nationality, nor any government, gives them to you), to pursue fair trails, and to be accountable for mistakes, and to perform justice through a court system where it can be seen for the good thing it is. It is not outrage for outrage's sake.
