Harmful idiocy syndrome is a widespread disease that affects many political commentators. There are several pathogenic and environmental causes. "Zero-tolerance" dogma is a main pathogen, whether applied to speech, social behaviour, political organizing, risk abatement, violence used in actual self-defence, or state violence in defending state sovereignty against a murderous attacker or invader. The pathogen is often spread by manipulative politicians and lobbies, and often incubates in institutional habitats, such as universities. The disease is part of the social engineering geography of Western states, and its many features have a variety of common names.
