@farmerman,
I think one of the main differences in attitude is what happens when you go looking for something. IDers are already convinced that they're right, and have always looked to science to prove that they're right. So they only look for things that prove they're right. All that furore over God's message in March Of The Penguins is a case in point.
Darwin wasn't looking for evidence to prove evolution, evolution occured to him during his research. Some people call it red mini syndrome. (You never notice how many people drive around in red minis until you start looking for them. Then, because you're so busy looking for red minis, you don't notice all the other cars, just the extrordinarily high proportion of red minis.)
