What types of speech are not protected by the First Amendment?

The First Amendment to the United States Constitution protects a wide range of speech, but it does not provide protection for certain categories that are considered harmful or disruptive to societal order. The correct answer identifies specific types of speech that fall outside the protections of the First Amendment.

Obscenity is not protected, as it fails to meet the community standards of decency and lacks serious literary, artistic, political, or scientific value. Defamation involves false statements that damage someone's reputation, and since it can cause real harm, it is also not protected. Fighting words are defined as speech that incites immediate violence or disorder, making them unprotected due to the potential for harm. Incitement to imminent lawless action refers to speech that urges or promotes illegal activities that are about to occur, and this too is not shielded by the First Amendment because it poses a direct threat to public safety and order.

The other options describe types of speech that are generally protected. Political commentary, parody, art, religious speech, commercial speech, and academic discussion often fall under the umbrella of free expression because they contribute to the marketplace of ideas and public discourse, even if they may sometimes be contentious or controversial. Truthful statements about public figures and criticism of government are also protected,
