In the 1969 Case of Brandenburg V

A) the First Amendment provides no protection for "fighting words" because such words "are no essential part of any exposition of ideas."
B) the Alien and Sedition Acts, which made it a crime to say or publish anything that might defame the government, were an unconstitutional violation of the First Amendment.
C) as long as speech falls short of actually inciting action, it cannot be prohibited, even if it is hostile to or subversive of the government and its policies.
D) the First Amendment does not require schools to permit students to advocate illegal drug use.
