Because, of course, truth is determined by polls...
Well, at least the creationists think it is, they keep turning to polls to "prove" that they must be right.
Scientists, on the other hand, think that truth is better determined by a careful examination of the vast amounts of evidence from the real world, and countless validation tests performed in every conceivable way in order to find out which explanations actually fit the facts and actually work when applied in reality.
Who's more likely to actually find truth?
What leads you to believe the ID movement is interested in the truth?
I think I know why the average anti-E denigrates scientific truth while promoting "revealed truth" -- the latter requires absolutely no intellectual rigor, and makes one feel good about oneself. Sort of like government school self-esteem programs or Kent Hovind's Ph.D.
