A bigot is a person who is obstinately and irrationally, often intolerantly, devoted to his or her own religion, political party, organization, belief, or opinion, especially one who regards or treats those of differing devotion with hatred and intolerance.[1] Bigotry is the corresponding mindset or action.
The term bigot is often misused to pejoratively label those who merely oppose or disagree with the devotion of another. The correct use of the term, however, requires the elements of obstinacy, irrationality, and animus toward those of differing devotion.
The origin of the word bigot and bigoterie in English dates back to at least 1598, via Middle French, and started with the sense of "religious hypocrite". Forms of bigotry may have a related ideology or world views.
