What type of speech is not protected by the First Amendment?

The First Amendment protects a wide array of speech, but there are certain categories that fall outside its protection. One of these categories includes hate speech that incites violence. This type of speech is not protected because it poses a direct threat to public safety and can lead to imminent harm. The government has the right to restrict speech that incites others to commit violence, as it can disrupt social order and lead to significant consequences.

In contrast, political speech is broadly protected due to its essential role in a democratic society. Citizens are encouraged to express their views and opinions on political matters, even if those views are controversial. Commercial speech, while subject to some regulation, does enjoy a certain level of protection, especially when it pertains to the dissemination of truthful information about lawful products or services. Artistic expression, similar to political speech, holds strong protection under the First Amendment because it fosters creativity and individuality, even if the content may be provocative or offensive. Hence, hate speech that incites violence stands out as the clear exception among the options listed.
