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.
White supremacy is the conscious or unconscious belief or the investment in the inherent superiority of some, while others are believed to be innately inferior. And it doesn't demand the individual participation of the singular bigot. It is a machine operating in perpetuity, because it doesn't demand that somebody be in place driving. Michael Eric Dyson
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
