I don't see four paragraphs of explanations on freedom of speech in the Bill of Rights. It's short and succinct.

Amendment I

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.

That's it. Argue until you're blue in the face, it still doesn't change the fact that it's so broad that it covers erotica too.
