I think we’ll have to agree to disagree on vagueness. “Freedom of speech” and “Freedom of the press” could mean a lot of different things, and historically these phrases have never really been interpreted by the US judiciary as conferring absolute rights. We're interested here in which rights are
actually conferred by the US constitution as interpreted by the courts, not in which rights someone could potentially read into the document. Nobody is protected by their own personal interpretation of the US constitution.
>To say it makes no difference is to ignore the significant differences between how U.S. and UK courts have ruled on individual speech rights. UK defamation law, for example, is significantly more in favor of plaintiffs than in the U.S.
I didn’t ignore this - I mentioned it in my comment. But I’m not convinced that that has anything much to do with the language of the First Amendment vs Article 11. After all, the First Amendment also does not protect libel - it’s just a difference in how broadly libel is construed in Britain vs. the USA. You won’t find anything in the text of the First Amendment that tells you exactly where libel stops and First Amendment rights start. For that you have to look to prior court judgments.
