Many parents (and students) do not want evolution taught.
Don't they count?
Fine! I really have no problem with that. If the parents sign a "No Evolution" document to the school district and the kids receive only plant and animal biology instruction, sans evolution, it's OK by me. As long as the parents and children understand that the school district cannot be held liable if these kids don't pass many of college entrance exams. The other students in the school would be taught current biology, including evolution, in other classrooms.
