Actually if you look up Fundamentalist (Fundamentalism), the definition is ... 1. (sometimes initial capital letter) a movement in American Protestantism that arose in the early part of the 20th century in reaction to modernism and that stresses the infallibility of the Bible not only in matters of faith and morals but also as a literal historical record, holding as essential to Christian faith belief in such doctrines as the creation of the world, the virgin birth, physical resurrection, atonement by the sacrificial death of Christ, and the Second Coming.

So the way I see it ... they're basic philosophy is no different than ANY Christian based religion ... their practice is different. But then again, all religions practice differently.
