Earlier quoted context omitted.
Are you arguing against the entire legal concept of libel/defamation?
When I was in law school, in the before times, libel and defamation were treated as a holdover from British common law. We learned how they had been winnowed down in the long “arc of justice,” starting with the Zenger trial in 1735. This trend of weakening libel and defamation laws, and any constraints on speech, was treated as uniformly positive.
("Guilty" may be the wrong word, because it's not a criminal offense, but I'm not sure what the right one is here.)
