But that's not what "ID science" claims. They specifically reject natural evolution. They say that complex life forms could not have evolved naturally. You can call this an anti-ID backlash if you want. What I'm against is their rejection of science in matters that are well settled.
Now here is what I think problematic about this type of argument. We can begin with a distinction between design exclusion and design denial. Design exclusion just says that design is not brought into a scientific explanation for, say, why the bacterial flagellum works the way it does. If that's the case, then science can't say that the B-F was designed (since that would be not to do science), but it also can't say that it wasn't. If we are adhering to a strict methodological naturalism, then all we can say is that since we're science over here, we can't make design part of the explanation for the B-F. The question of design is left outside the competence of science. Many people in science adhere to this kind of a position. Some are theists and some are atheists. Operating this way, it is easy to get to the conclusion that naturalistic evolution is the best science, because it's the only game in town by definition. The result is some version of NOMA (non-overlapping magisteria). Consistently applied this leads to a kind of "language game" perspective where scientists are playing the scientific language game, but that wouldn't prevent someone from playing the religious language game and affirming creation. The claim that one perspective or the other represents reality would be regarded on this view to be a mistake.
But methodological naturalism gets challenged on both sides. People who think science should affirm a designer are going to see this as an unjustified limitation on science, and also those, like Dawkins, who argue that the evidence of evolution reveals a world without design have to argue that science could have reached the opposite result if the evidence had been different. But then we have to go back through the history of biology to figure out whether the dog is wagging its tail or the tail is wagging the dog. Did naturalistic evolution become the only game in town because of methodological constraints, or would scientists have found design if only it had been there. Because methodological arguments have so often been used in defense of evolution, I consider it unfair to call ID advocates IDiots, since they are asking a perfectly legitimate question.
