Yes, I'm not in the US. But I think I didn't express myself clearly. Actually, what I mean is more something along the lines: "people should be held accountable by what they spread". Things like defamation are punishable in the US, right?
Also, in the USA, truth is an absolute defense to a defamation claim. The burden of proof is on the plaintiff to prove that the speaker was wrong, and further, in most cases, that the speaker should have known that it was wrong.
People like to talk about "defamation", but in America the bar is so high that it's only rarely applicable.
