Lawful, peaceful and meaningful demonstration is an American right of dissent.
Stupid persons making a jackass out of themselves and destroying other's property is unlawful.
I don't mean demonstration in that context. I mean it on a smaller, personal level like "you seem pressed for time. Why don't I go and do___ for myself rather than you pushing yourself to do it" and the reaction was very poor and downright angry as if I were actually expressing impatience. You see?
