I believe the citizens of those countries might respectfully disagree.

The US is somewhat absolutist relative to the global average on this topic (and even the US isn't complete freedom of speech---pornography law exists, as do various extremely tight constraints on pedophilia imagery).

As a citizen of a European state I can guarantee you that close to everyone here is very aware that we don't live in a legislation that permits free speech. If america decides that they're limiting their speech as well I wouldn't know where to go to discuss. The darknet, presumably, or maybe some shell company on an island nation that rents servers.
