You’re right, as established in cases like Brandenburg v. Ohio, Schenck v. United States, Chaplinksy v. New Hampshire, etc, and the one thing all of them have in common is they are content based restrictions when they incite imminent violence or a clear and present danger, the government can’t restrict speech just because it’s hateful or inflammatory
The issue isn’t whether hate speech is bad, I think most people can agree it is. The issue is giving the government the authority to decide which opinions or language are unacceptable. Once that precedent exists, the definition can expand well beyond obvious slurs are hateful statements depending on who’s in power.
