As a thought experiment, consider what a hoplite educated in a Spartan agoge would think of your views. What about an aristocrat educated in Antonine Rome, or in France under Louis XIV? Would they share your sanguine views on the wisdom of the People? If not, why not? How confident are you that you are right and they are wrong, and what is the basis of that confidence?
None of this is a defense of current Chinese government policy. My point is that using official education for brainwashing and political indoctrination is par for the course in a country founded on the principle of popular sovereignty. One consequence of this is that virtually every educated Westerner, including most readers of Hacker News and the New York Times, has been exposed to the same sort of brainwashing and political indoctrination decried by the protesters in the OP. One effect of this is a reflexive support of popular movements of all sorts without an appreciation of the potential costs of that support.
Louis XIV might even have been sanguine, but his descendant Louis XVI would know what I mean.
Ultimately though you are going to run into debating philosophy and that makes for wonderful rhetoric but few conclusions.
The "large amounts" can be a figure media put out of their asses.
Take Putin, as a case in point. He has the majority vote by a large margin, the common people love him, but in western media he is portrayed as a dictator.
E.g they take some pro-westernization demonstrations of 10,000 people and blow them out of all proportions. The equivalent would be to use the "Occupy Wall Street" footage as proof that the majority of Americans are against their leadership and the country is a dictatorship.
It doesn't hurt that the minority of Russians that americans find closer to them and their views are anti-Putin. For them, those people (bloggers, tech-geeks, young westernised people etc) represent what most Russians want, when in reality they represent a small minority.
Good government policy involves enough stakeholders, and propose reasonable enough solutions, that there's no reason for protests. So while certainly not every large protest is 100% right, they usually do indicate a breakdown of effective processes for representative government, as applied to the policy area in question.
