Question: A member of the KKK is about to speak at a public forum. Some people have threatened to riot because of the speaker. May the city cancel the speaker's forum? Yes, because the speech is likely to cause harm. Yes, because the speaker is likely to say things that are "fighting words". No, the city may stop it if a riot breaks out, but they cannot stop speech beforehand because of a "heckler's veto." Yes, because hate speech is not protected speech under the 1st Amendment. No, your right to free speech is absolute, and the city may never stop it
