I'm not sure what you're trying to argue. Under Classical Liberalism (which I am a proponent of), if your speech violates the Harm Principle, it's not protected. Conspiracies are indeed protected speech (e.g. "CIA killed Kennedy"). If your conspiracy incites to violence ("CIA killed Kennedy, let's storm Langley" -- and people actually do it), it's no longer protected speech.

I said exactly what I meant to say. Saying that the government ought to be overthrown is a long protected American right. The book stores are full of books arguing just that. People taking you up on it is not your problem.
