...because trying to curtail freedoms is immoral, right? All of the Amendments are moral statements. The whole Constitution is, except for some procedural matters. The Declaration of Independence is about morality. All men are entitled to life, liberty and the pursuit of happiness? Hitler didn't believe that. Stalin didn't believe that. A lot of the contemporary Left don't believe that, and that's why we consider them all to be immoral men.
Same thing. Ensuring the existence of a free society is a moral value judgment. Although I'm curious what you'd think of this - if you and I were stranded on a desert island with no hope of returning to society, would it be immoral if I killed you? (I know it sounds crazy to kill your only human companionship, but maybe I don't want to share limited food, or maybe you're just too annoying.
