Fanaticism
Fanaticism is the obsessive or uncritical belief towards something or someone. It came from the Latin word “fanaticus” which means “of a temple” or “inspired by a god” as fanatic originally referred to being possessed by a god or a demon. In history, religious fanaticism has led to violence as rival believers were killed. Currently, fanaticism also pertains to having an extreme interest about something. For instance, the man’s dog fanaticism was the culprit of his marital problems. In modern usage the term fanaticism (the term "fan" is short for fanatic) is often felt about athletes, sports teams, musicians and other celebrities. This great flow of emotion has, in recent years, led to many riots and accidental deaths.
