Don t attack fundamentalists as if they were fools. Often biblical literalism is an attitude of self-defense even on the part of extremely intelligent people. They want to preserve their faith in God, and this seems to them the only way. They will understand your attacks on them as an attack on their faith. Indeed, were you to be successful in convincing an intelligent biblical fundamentalist that the position is wrong, you might be surprised to find that the former fundamentalist does not become a more moderate Christian but an atheist.
Some fundamentalists are very well informed about biblical technicalities, such as languages.
There are occasionally evangelists who know a lot more about the Bible than the average Catholic priest or mainline Protestant minister. Don t be sure that your standard arguments against fundamentalism will work. Biblical fundamentalists have developed careful defenses against the contrary arguments that they have encountered. For instance, if you triumphantly point to the fossil argument supporting evolution, you may be surprised to find a fundamentalist who maintains that God created the world with fossils already in it and that therefore such fossils tell us nothing about the antiquity of the world. There is no use moaning about the number of fundamentalist media preachers if we have no one in the media presenting the Bible in a sensible, nonliteral manner based on modern biblical approaches, and not simply using the text as a jumping-off point for a pietistic homily.
