1.2. The Pledge of Allegiance

2. Cultural diversity
2.1. "the purpose of public education religion studies is to prepare young people for confrontation with religious diversity within the public realm and enable them to handle it without having to be either offensive or defensive about religion" Professor Dale Cannon
3. Curriculum debates
3.1. Theory of evolution versus creationism
3.1.1. "There are...sound scientific and pedagogical reasons why both models should be taught, as objectively as possible, in public classrooms, giving arguments pro and con for each. Some students and their parents believe in creation, some in evolution, and some are undecided. If creationists desire only the creation model to be taught, they should send their children to private schools which do this; if evolutionists want only evolution to be taught, they should provide private schools for that purpose. The public schools should be neutral and either teach both or teach neither." Henry Morris
