Nothing makes us believe more than fear, the certainty of being threatened. When we feel like victims, all our actions and beliefs are legitimized, however questionable they may be. Our opponents, or simply our neighbors, stop sharing common ground with us and become our enemies. We stop being aggressors and become defenders. The envy, greed, or resentment that motivates us becomes sanctified, because we tell ourselves we're acting in self-defense. Evil, menace -- those are always the preserve of the other. The first step for believing passionately is fear. Fear of losing our identity, our life, our status, or our beliefs. Fear is the gunpowder and hatred the fuse. Dogma, the final ingredient, is only a lighted match.
