Scratch the paint of a liberal and you’ll find an alienated fundamentalist underneath.
The three contemporary streams of American Protestantism (fundamentalist, liberal, and evangelical) lead to very different ideas about what the country’s role in the world should be. In this context, the most important differences have to do with the degree to which each promotes optimism about the possibilities for a stable, peaceful, and enlightened international order and the importance each places on the difference between believers and nonbelievers. In a nutshell, fundamentalists are deeply pessimistic about the prospects for world order and see an unbridgeable divide between believers and nonbelievers. Liberals are optimistic about the prospects for world order and see little difference between Christians and nonbelievers. And evangelicals stand somewhere in between these extremes. (Source.)
