What does the sticker say?
"This textbook contains material on evolution. Evolution is a theory, not a fact, regarding the origin of living things. This material should be approached with an open mind, studied carefully and critically considered."
The sticker itself, to me is immaterial.
I've got a problem with the whole politicization that has happened, first at the hands of school board members, and now, at the hands of a federal judge.
As far as worrying about my kids knowing about God's hand in Creation is concerned, I'd suggest the school board stay out of parenting my children. My wife and I have made certain that they DO know.
Just get back to teaching "the three 'R's" and be done with it.
