Protesters are not only bringing a message, but almost always proposing a solution. And in both cases you mention they are vigorously pointing out the frying pan while being willfully blind to the fact that they're trying to get us to jump in the fire.

It's possible to have a protest movement over somebody protecting an ox, but most protests are about issues that aren't solved because there is no good solution. If there is an answer why hasn't it been done?
