That's why we have polls and statistics, instead of relying on the "most vocal" and supposedly "most courageous" people that "brave" the streets to protest. I personally don't buy it.
Any political poll conducted on an authoritarian state will not be trustworthy either. It's like going to a black neighborhood on the US and doing a poll on marijuana use. Many people will not admit to illegal activity. This is something an statistics professor will say in any basic introductory course.
