We do have laws against hate speech. It's just that what he's doing isn't hateful. If he had been spreading slander or something, it would be different.
Huh? No, we don't, unless the speech is an incitement to imminent violence or defamation:

@SCG: Good article, and my sentiments exactly. Honestly, I really don't care about Jones. He's obviously an attention whore, and the fact that he managed to rocket himself to worldwide fame in a few short days while keeping himself out of jail actually earns him a modicum of my grudging admiration. The media just fucked this whole thing up.
