Where no shadow of doubt is allowed; you can be sure fanaticism will loom large in its place
Fanaticism refers to a person or organization that is no moderate, instead a fanatic is obsessed with a specific idea, person, or ideology. Everything in life requires moderation, and fanaticism refers to going too far with an idea or a principle so that it becomes harmful or dangerous. Terrorists engage in fanaticism, and some of the most devastating events in history including WWII were a result of this as well.
