We're not just talking about basic political speech freedoms, there's plenty of gray area about. For example, the US and UK both have laws on libel/slander (I think most countries do), but the US is much more permissive than the UK, in the sense that it's a lot harder to prove that someone committed libel/slander. Is it a "human right" to maliciously and publicly lie about whether some other person, say, killed a child for fun? You could certainly argue "people should be able to say whatever they want whenever they want", but I think most people would agree that some restrictions on that kind of speech is reasonable, because it ends up harming others.
