Peter, I'm with Voltaire, but only most of the time and I do not follow your either/or argumentation. You are consistent in your position but I do not agree with you here.

We have had our very special experience with language inciting hatred and promoting actions in gross violation of human rights. In our culture/system, such language wouldn't have the law on its side even if this language was rhymed, sung or processed/refined in some other way to make it 'art'.

Our law would in such (thankfully very rare) instances see an equivalence to the crying 'fire' situation for in both situation the language is used to make other people do something which is dangerous to themselves (or others).
