A parent has decided that because of the unanimous vote to keep the book in place, the system must be flawed!
I find fault with this parent's way of thinking. Just because something is unanimous does not mean that it's a failure of democracy. A review committee is, in some ways, like a jury. While it does not have to decide unanimously, each member must provide all of their reasoning for their decisions regarding the book, and in doing so, some members may be persuaded of certain things or swayed in a direction they did not originally intend to go.
What did make me happy in this case, was the Superintendent's decision to actually follow policy and defend the decision, telling Mr. Krueger that "once a book has been challenged and a determination made, it cannot be challenged again for two more years."
There you have it parents, if you don't like the book and you feel it's just too unfair somehow to opt your own kid out of reading it, go ahead and come back in two years to try and take it away from every other child in the district again. K, thanks, bye.
