“A person who is obstinately and unreasonably wedded to a particular religious or other creed, opinion, practice, or ritual; a person who is illiberally attached to any opinion, system of belief, or party organization; an intolerant dogmatist.”
Perhaps they are cut from the same cloth as those who enthusiastically guillotined perceived enemies left and right during The Terror, only to be beheaded themselves months later by other revolutionaries using the same justification and sense of righteous fervor.
