A person who regards his own faith and views in matters of religion as unquestionably right, and any belief or opinion opposed to or differing from them as unreasonable or wicked. In an extended sense, a person who is intolerant of opinions which conflict with his own, as in politics or morals; one obstinately and blindly devoted to his own church, party, belief, or opinion.

We call a man a bigot or a slave of dogma because he is a thinker who has thought thoroughly and to a definite end. Gilbert K. Chesterton
Bigot: One who is obstinately and zealously attached to an opinion that you do not entertain. Ambrose Bierce
He that cannot reason is a fool. He that will not is a bigot. He that dare not is a slave. Andrew Carnegie
