Religious bigotry has been evidenced throughout history; Jews have often been the target. Political bigotry exists most commonly under totalitarian regimes headed by people with extremist positions. Class bigotry, in addition to the obvious caste system, is often discernible in labour - management conflicts and in the attitude of one national group to another.
Bigotry is an intolerant, obstinate, and unthinking attachment to one's views, party, or religion. It is heedless of truth, flouts the obligation to treat one's fellow man with sympathy and love, and is highly disruptive of social unity. Bigotry involves powerful emotions, thus is easy to incite. It stems from various causes, often begun at home, developed in school, and maintained by the media and governmental laws.
