@Bananas@Hudson well said. People are angry at the establishment, but they share part of the responsibility. Even though there are plenty of reasons for people to be angry and agitated, I'm afraid that in the cases you mentioned, the people are being manipulated by demagogues to whip them into an agitated mob and steered into a direction that offers no solutions to their problems. It's like, let's burn down the house, because there are termites..
When someone is angry, agitated, scared, etc, but without good knowledge or training, they most likely make serious mistakes, rush to judgment, and can be easily manipulated. Practicing citizenship requires serious and responsible effort.
