Incitement to Riot is not protected "free speech"

[Warren DeMontague]

30. The related concepts of "incitement" & "Fighting Words" have been significantly narrowed since 1917

The SCOTUS in the last 100 years has taken a much broader view, than the WWI era judiciary, of the protections of the 1st Amendment.

You will note that similar statements to the Espionage Act, i.e. objecting to the draft, have been ruled to be protected speech in subsequent decisions.

The court has continued to uphold the doctrine but also steadily narrowed the grounds on which fighting words are held to apply. In Street v. New York (1969),[3] the court overturned a statute prohibiting flag-burning and verbally abusing the flag, holding that mere offensiveness does not qualify as "fighting words". In similar manner, in Cohen v. California (1971), Cohen's wearing a jacket that said "fuck the draft" did not constitute uttering fighting words since there had been no "personally abusive epithets"; the Court held the phrase to be protected speech. In later decisions—Gooding v. Wilson (1972) and Lewis v. New Orleans (1974)—the Court invalidated convictions of individuals who cursed police officers, finding that the ordinances in question were unconstitutionally overbroad.

In R.A.V. v. City of St. Paul (1992), the Court overturned a statute prohibiting speech or symbolic expression that "arouses anger, alarm or resentment in others on the basis of race, color, creed, religion or gender" on the grounds that, even if the specific statute was limited to fighting words, it was unconstitutionally content-based and viewpoint-based because of the limitation to race-/religion-/sex-based fighting words. The Court, however, made it repeatedly clear that the City could have pursued "any number" of other avenues, and reaffirmed the notion that "fighting words" could be properly regulated by municipal or state governments.

In Snyder v. Phelps (2011), dissenting Justice Samuel Alito likened the protests of the Westboro Baptist Church members to fighting words and of a personal character, and thus not protected speech. The majority disagreed and stated that the protester's speech was not personal but public, and that local laws which can shield funeral attendees from protesters are adequate for protecting those in times of emotional distress.
Incitement vs. fighting words

Incitement is a related doctrine, allowing the government to prohibit advocacy of unlawful actions if the advocacy is both intended to and likely to cause immediate breach of the peace. The modern standard was defined in Brandenburg v. Ohio (1969), where the Court reversed the conviction of a Ku Klux Klan leader accused of advocating violence against racial minorities and the national government. The Ohio statute under which the conviction occurred was overturned as unconstitutional because "the mere abstract teaching of the moral propriety or even moral necessity for a resort to force and violence, is not the same as preparing a group for violent action and steeling it to such action."[4]
