Which types of speech are not protected by the First Amendment?
Although different scholars view unprotected speech in different ways, there are basically nine categories:
- Fighting words
- Defamation (includes libel, slander)
- Child pornography
- Incitement to imminent lawless action
- True threats
- Solicitations to commit crimes
Some experts also would add treason, if committed verbally, to that list. Plagiarism of copyrighted material is also not protected.
