bigot
n. A person who is religiously attached to a particular
computer, language, operating system, editor, or other tool (see
religious issues). Usually found with a specifier; thus,
`cray bigot', `ITS bigot', `APL bigot', `VMS bigot',
`Berkeley bigot'. True bigots can be distinguished from mere
partisans or zealots by the fact that they refuse to learn
alternatives even when the march of time and/or technology is
threatening to obsolete the favored tool. It is said "You can
tell a bigot, but you can't tell him much." Compare
weenie.
