Constitutional attorney Brian Fahling has a sensible discussion of the Cobb County decision in the Union-Leader, here. Especially pertinent is his paragraph responding to the charge that it was illegitimate for the school district to single out evolution in its disclaimer. Fahling hits the proverbial nail on the head when he says:

I suspect that evolution was singled out because it is the only scientific theory whose adherents are utterly intolerant of criticism, and it is the only scientific theory taught in public schools as the gospel truth that no reasonable person could question. This is not only troubling for parents whose religion rejects the theory, but it is equally troubling from an academic, scientific, and intellectual perspective for obvious reasons.
