First Amendment to the United States Constitution:

“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.”

With such a broad definition of what constitutes speech and who is protected by speech, I have to ask: then what part of not prohibiting “the right of the people peaceably to assemble” do they not understand?
