Freedom of speech is not given the same primacy as it is in the US in other countries; while it is a right everywhere, for example the ICCPC you cited also has Article 20: >Any advocacy of national, racial or religious hatred that constitutes incitement to discrimination, hostility or violence shall be prohibited by law. Germany has even stronger caveats to freedom of speech. The US stands alone (to my knowledge) in the way it treats freedom of speech because of the wording and interpretation of the first amendment, which is why there is so much debate in the field of first amendment jurisprudence and philosophy as to what its limits are and what they, in the views of many researchers, what they should be. See Susan Brison's arguments on that point. Countries such as the UK and Germany frequently allow concerns of discrimination, the silencing power of speech, and other factors to override pure freedom of speech. To my knowledge, the bill of rights only applies in England and Wales, and it is extremely infrequently used, and hasn't been, to my knowledge, used to protect freedom of speech (at least not any time recently).
