I must say I have never heard the word "bigot" being used among my Singaporean friends. Neither have I used it before. The word we might use which is closest in meaning that I can think of would be "Obstinate". Probably because of our limited vocabulary. Come to think about it, an ex-colleague of mine many years ago is a perfect example of a "bigot" - obstinacy, irrationality, and animosity toward those of differing opinion. He must alway be "right". In fact I nickname people like that "Porcupine" LOL.
From Wikipedia, the free encyclopediaA bigot is a person obstinately or intolerantly devoted to his or her own opinions and prejudices. The correct use of the term requires the elements of obstinacy, irrationality, and animosity toward those of differing opinion. The term is also used to refer to persons hostile to people of differing race, ethnicity, nationality, sexual orientation, religion etc.
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.
