You won’t be surprised to learn that I think protesting is a waste of time, an exercise in self-indulgence that gives people a way to feel good about themselves for ‘doing something’ without actually accomplishing much of anything. While it may be therapeutic for the person with the sign, shouting about what (or who) you hate at the top of your lungs seems unlikely to effect change. It’s more likely to be treated like a temper tantrum: You may get placated, but you’ll never get respect.
