Which of the following is an example of protected speech?

Political protest speeches are an example of protected speech because they are a fundamental aspect of the First Amendment, which guarantees freedom of speech and expression. This protection allows individuals to express their opinions, advocate for social change, and critique the government without fear of censorship or retaliation. The Supreme Court has historically upheld the rights of individuals to engage in political expression, even when that speech may be unpopular or controversial, as it is essential for a functioning democracy.

In contrast, inciting violence, obscenity, and fighting words do not receive the same level of protection under the First Amendment. Inciting violence poses a direct threat to public safety, obscenity lacks serious literary, artistic, political, or scientific value, and fighting words are seen as likely to provoke immediate violence or disturbance. Therefore, these forms of expression can be regulated or restricted by law.
