The great test of all protest is whether it is truly instructive to the society it challenges. Protest should enlighten society about those problems that its bigotries and ignorance keep it from facing--problems it must grapple with for its health and survival. When protest is truly instructive, it gives society a much greater vision of itself. It doesn't just complain. It says this society is already great (or protest would be a waste of time), and this is how much greater it will be when the problem being protested is solved. Truly instructive protest is exciting and flattering for everyone because it holds out the possibility of personal and social growth.
Potential protesters should consider this when they make their plans.
