Pretty much every idea*, however stupid, false or abhorrent, deserves political (i.e. legal) respectability. No one ought to be punished in a strictly political sense for saying just about anything. Political respectability, at least in a free society, deserves to be taken for granted. The assumption of political respectability goes not only to the expression of ideas, but the criticism of others' ideas: just because I criticize an idea does not mean I advocate withdrawing political respectability from that idea. This position stands in contrast with the ethical criticism of actions: to criticize an action entails advocating withdrawing political respectability for that action and making it illegal.
*With the usual exceptions of libel, slander, conspiracy and shouting "Fire!" in a crowded theater.
Because of this principle I tend to find criticism of how someone says something to be tedious and irritating. If someone says something, they said what they wanted to say the way they wanted to say it. If you want to say something different in a different way, just say what you have to say in the way you want to say it. The whole framing debate fills me with aggravation and nausea; people such as Nisbet and Mooney simply do not understand freedom of speech in any deep, philosophical way.
