Definition for Fundamentalism

The#mce_temp_url# link is for a video by Seth Godin who talks about Curiosity and Fundamentalism.  While I do not agree with everything on the video, I did find it helpful in regards to defining fundamentalism for me.  Do we inside of Christendom care more about “how it will look” rather than “is it truth”?  Do we hold tight to our “traditions” because they are more comfortable or because God uses them to change the world?
