From Noah Webster's first dictionary in 1828:
1. A person who is obstinately and unreasonably wedded to a particular religious creed, opinion, practice or ritual. The word is sometimes used in an enlarged sense, for a person who is illiberally attached to any opinion, or system of belief; as a bigot to the Mohammedan religion; a bigot to a form of government.
Since dinosaurs bother you SOOO much, here's one to stomp on that last nerve, scientifically and locally, with no mention of religious opinion AT ALL!
Find out just what any people will quietly submit to and you have the exact measure of the injustice and wrong which will be imposed on them. - Frederick Douglass
