Sorry, lassy, you are not protected from an offending message. The threat or action of physical force is an entirely different matter.
Well, actually, in some cases which have now passed constitutional muster, you are. Some municipalities and counties have established 4th degree assault, which amounts to causing undue annoyance. You may tell me something once, politely. You may not pursue me down the street exercising your freedom of speech in my vicinity for a half-hour.
