What is a "fundamentalist"? I see the term tossed around all the time with no attempt to objectively define it. Generally, it's just used by the secular world as a pejorative epitaph. If it just means someone who believes in the fundamentals of Christianity, then who would ever deny being a fundamentalist?
A Fundamentalist, as I see it, is one who adheres to the theology set forth in a series of books entitled The Fundamentals: A testimony to the Truth (Reuben Torrey and A. C. Dixon, eds., Los Angeles: Bible Institute, 1917). I don't normally give references to "wiki"-type resources, but Theopedia has a pretty good summary of the series, available here
