Eric reed and Colin Kaepernick demonstrated what first amendment when they kneeled during the national anthem

They demonstrated the First Amendment. The First Amendment prevents Congress from making any law prohibiting the free exercise of religion, or the freedom of speech, the freedom of the press, the right to peaceably assemble, or petition.
