I feel most of us have been conditioned to prefer only the mildest and most inoffensive ways of protesting as valid and consider the rest impossible. In my view, governments today ignore protests because they don't actually threaten anything. A protest with teeth might be mass absenteeism from work, refusing to pay taxes, something that actually hurts.. although in this case it's probably a bit much, when the threat of real protest is completely gone you end up with authoritarian governments.
