Frankly I don't beieve there should be public schools. I also believe that parents should have the right to move their children out of a school or a district if they don't like the curriculum or the number of gang members. that would resolve most of these disputes over curriculum. I also believe that if the government is going to fund the education of children that there should be no discrimination against religion and that the money that would otherwise go to the public schools should be sent to the private school that the child attends.
This case was not even about a curriculum. It was about a statement that was required to be read by the teacher before the teaching of evolution which set forth the position of the school board.
Said statement did more than represent the "position of the school board". The school board required the teachers to represent ID as a viable alternative scientific theory, and the defense chose to rely on the viability of that claim, which required the judge to assess it.
