Shitstorms have only become possible through the internet. Mass protests are accompanied by insults and obscenities. A shitstorm can affect individuals and institutions, even if they do everything right. The book explains the phenomenon of the shitstorm - it arises from the buildup of anger in online forums that do not allow dissenting opinions. Unique cultures with distorted worldviews and enemy images emerge here. At certain events, the pent-up rage is unleashed. It is solely about protest and not about a discussion - this is the opposite of what the internet was originally intended for. How do areas with uniform worldviews develop? How are many people mobilized for protest? Who actually participates and what are the reasons for it? Can the intensity of the uprising be softened? The author illustrates the issues with vivid examples.
