Which amendment guarantees freedom of speech?

The First Amendment is fundamental to the framework of American democracy as it establishes several core freedoms, one of which is freedom of speech. This amendment prevents Congress from making laws that infringe upon the freedom of expression, allowing individuals to speak their minds, share ideas, and engage in debate without fear of government censorship. The protection of speech is essential for a healthy democratic society, where diverse opinions can coexist and be discussed openly.

While other amendments address important rights and protections—such as the right to bear arms, protection against self-incrimination, and prohibitions against cruel and unusual punishment—none specifically focus on the fundamental right to freely express one's thoughts and opinions, which the First Amendment explicitly ensures.
