I think this author is overly simplistic and dismissive. I don't see them illustrating a "proper" way of protesting, in fact seeming to go as far as saying that protests themselves are useless. And with that I firmly disagree. Many changes in our society only came about due to protest (and usually "nuissance" protest, as nobody changes for a protest that can be ignored). That doesn't mean all protests are for good or worthy causes, but protests are a way for anyone who may not have power otherwise, to help influence society.
