What in your own words is a fundie and what in your own words is a Christian. I don't want link, or a plagiarism. I want your own words.
Why are my words important? What if someone explains it better than I can?
The short version is that fundamentalism is a modern day "cult". It did not exist as such before the mid 1800's. Fundamentalism imposes modern day beliefs and ideas on the Bible (example: literalism) that did not exist in the time of the writers of the Bible. Fundamentalism also emphasizes the teachings of Paul at the expense of the teaching of Jesus. Jesus taught love, forgiveness, equality, "us" not "them" and a morality based on those principles. Paul's teachings are more judgmental, emphasizes they are different & ergo wrong, only WE are right, accept and love only the deserving, not all people.....
I sometimes call fundamentalist "Paulists", but that is really not fair to Paul. He teachings are not that bad until seen through the light of literalism.
I hope that helps.
