Here are three rules you should know about "Hate Speech" and the First Amendment.

Rule 1. The First Amendment protects all ideas–loving, hateful, or in between.

Rule 2. Some speech is not protected by the First Amendment, but that’s true regardless of whether it’s bigoted or hateful.

Rule 3. Hate crime laws are constitutional, so long as they punish violence or vandalism, not speech.
