It sounds like you're trying to shift the goalposts of "peaceful" into "gentle" or "inoffensive".

You have a First Amendment right to "peacefully" scream the most awful insults you can think of at a police officer. The police officer feeling personally "antagonized" because it hurt their feelings? Sorry, that doesn't allow them to abuse the special power of their workplace you attack you. If they try anyway, that's a real crime.
