Final answer:
Freedom of speech is not absolute. There are limits on speech that incites criminal acts, constitutes 'fighting words,' or poses genuine threats. Content-based limitations on speech are allowed in certain circumstances.
Step-by-step explanation:
Freedom of speech is not absolute, and there are several key restrictions on it. While the Constitution protects most forms of offensive and unpopular expression, there are limits on speech that incites criminal acts, constitutes 'fighting words,' or poses genuine threats.
Additionally, defamation of character through libel or slander is not protected. However, content-based limitations on speech are allowed in certain circumstances, such as obscenity, subversive speech, or speech promoting violence against the government. Overall, while there are restrictions on free speech, it is important to strike a balance between protecting individual rights and ensuring the safety and well-being of society.
