I want to also make an observation about how rights are often used in the defence of the most horrific things. Rights aren't things to be verbally wielded around one's head; they require precision and definition and analysis. I'm often horrified that people quote Voltaire when they're wielding that right around their heads. They quote him and say he said, "I disapprove of what you say, but I will defend to the death your right to say it." He did use those words and he also supported criminal laws against libel, slander, incitement to violence, and treason. Some people quote Mill in the same regard, but yet he also announced the harm principle and spoke of preconditions to expression, which was framed in a responsible way before you exercised the right.
