Which of these rights is guaranteed to every U.S. citizen?

Freedom of speech is a fundamental right guaranteed to every U.S. citizen by the First Amendment of the Constitution. This amendment protects individual expression and the ability to communicate ideas without government interference or regulation. It is a cornerstone of democratic society, ensuring that citizens can engage in open dialogue and debate, which is essential for a functioning democracy.

In contrast, while the right to bear arms is protected by the Second Amendment, it has specific conditions and regulations that vary by state. The right to vote at 16 is not universally guaranteed across the United States; voting age is set at 18 by federal law. Lastly, the right to public education exists as a legal obligation in many states but is not explicitly outlined as a constitutional right. This makes freedom of speech a more universally applicable right among U.S. citizens.
