Sorry to be a bit late to the party, but in regards to fundamentalists and the Old Testament, what galls me is not so much favoring the "fire and brimstone" God of the OT vs. the compassionate, "peacenik" God of the New Testament, it's that they pick and choose.
Fundies, especially of the Sarah Palin ilk love to quote the apocalyptic prophets such as Joel or Daniel or Jeremiah, or rehash the destruction of Sodom and Gomorrah with great relish. Far more seldom do you see them pondering the social justice message of Amos (an angry lefty if there ever was one)or the implications of Elijah staying with the Widow of Zaraphath (God's mercy extends even to them furriners), just to name a few stories.
I believe the Bible as a whole shows us the follies of those who believe they are more righteous and therefore better than everyone else. To paraphrase another Old Testament verse: Pride goeth before a fall.
