In order to protect the free flow of ideas and opinions on matters of public interest and concern, the First and Fourteenth Amendments prohibit public figures and public officials from recovering damages for the tort of intentional infliction of emotional distress by reason of the publication of a caricature such as the ad parody at issue without showing in addition that the publication contains a false statement of fact...
See also Gertz v. Welch:
Under the First Amendment there is no such thing as a false idea. However pernicious an opinion may seem, we depend for its correction not on the conscience of judges and juries but on the competition of other ideas. But there is no constitutional value in false statements of fact.
