'Fire in a Crowded Theater' and Other Free-Speech Myths

The misunderstanding: "Free speech has limits. You can't yell fire in a crowded theater." People usually say this to argue that the government may punish speech that is offensive, hateful or dangerous. It is the most quoted line in American free-speech debates, and almost nobody who quotes it knows where it came from.

Where the line came from

The First Amendment is short and direct: "Congress shall make no law… abridging the freedom of speech, or of the press" (National Archives).

The "fire" line comes from Justice Oliver Wendell Holmes Jr. in Schenck v. United States (1919): "The most stringent protection of free speech would not protect a man in falsely shouting fire in a theatre and causing a panic" (Justia). Note the words "falsely" and "causing a panic," which usually get dropped. Note also what Charles Schenck actually did. He was a Socialist Party official who distributed leaflets urging men to resist the World War I draft. The Court upheld his conviction under the Espionage Act.

Holmes's line was an illustration, not the rule of the case. The rule it supported, the "clear and present danger" test as applied in Schenck, allowed the government to imprison a man for anti-war pamphlets. Few Americans on the left or right today would defend that.

The Court changed course

In Brandenburg v. Ohio (1969), the Court reversed the conviction of a Ku Klux Klan leader and set the modern standard. The government may not punish advocacy of force or lawbreaking "except where such advocacy is directed to inciting or producing imminent lawless action and is likely to incite or produce such action" (Justia). The decision protected repugnant speech precisely so that the government could not decide which unpopular ideas get punished, which is the same power that had been used against Schenck.

There is no "hate speech" exception

The Supreme Court has never recognized a general exception for "hate speech." In Snyder v. Phelps (2011), it protected the Westboro Baptist Church's vile funeral protests (Justia). In Matal v. Tam (2017), it unanimously struck down a federal ban on trademarks that "disparage" people. Justice Alito's opinion explained that speech demeaning people on the basis of race, religion or similar grounds is hateful, "but the proudest boast of our free speech jurisprudence is that we protect the freedom to express 'the thought that we hate'" (Justia).

That does not make all speech protected. In United States v. Stevens (2010), the Court listed the narrow, historically recognized categories that fall outside the First Amendment (obscenity, defamation, fraud, incitement and speech integral to criminal conduct), and it refused to invent new ones by weighing a category's "value" (Justia). (Other cases recognize a narrow category of "true threats.") That is originalist reasoning: the exceptions are the ones the founding generation's legal tradition already knew, not ones judges create as new controversies arise.

A second myth: "Free speech means a company can't ban me"

The First Amendment restrains government. In Manhattan Community Access Corp. v. Halleck (2019), the Court reaffirmed that the Free Speech Clause applies to state action, not to private parties (Justia). A private platform, employer or newspaper that moderates speech is not violating the Constitution, though a culture of free expression is a value worth defending in private life too. When the government pressures private companies to suppress speech, though, the First Amendment comes back into play.

The bottom line

The next time someone says "you can't yell fire in a crowded theater," ask two questions. Is the speech false and likely to cause imminent harm? And is it the government doing the punishing? If the answer to either is no, the old line doesn't apply. The Framers' rule is simpler and braver than the slogan: in America, the answer to speech you hate is more speech, not a government censor.
