NOOO! NOT OPEN DISCUSSION!! We will all descend into madness, and devolve back to the rank of protozoa!!! (sarc/OFF)
What is wrong with asking questions? What is wrong with sticking one's hands in the ground searching for clues? What is wrong with thinking for oneself, or perhaps even coming up with NEW THEORIES?
Nothing. Nothing is wrong with making new statements, asking "what if", creating new scenarios. It is entirely possible that no school would want to teach ID, but it is also possible that their motivations for doing so have little to do with science and more to do with agenda.
Schools have a right to teach whatever they like, but when they stifle creativity, innovation, and discussion, they cease to be schools. They descend to the rank of propagandism, and destroy science in the process...
