Freedom of speech an absolute? Right. No ifs and buts and wherefores and hereinunders? None whatsoever. No need to consider that with freedoms might come responsibilities? Exactly.
So let's look, all over again, at the classic case (thank you Oliver Wendell Holmes, Jr): can you falsely shout "Fire" in a movie theatre? "Falsely" -- meaning when there's no fire.
If you do so, are you protected by free speech statutes, example the US First Amendment?
If you won't do it, are we talking responsibility?
