This disgusts me.
American kids need to learn science. This is not science. It is deeply damaging to the future of our nation. We don't teach gravity as a theory that can be believed or not believed as one chooses. Gravity is a phenomenon that one should seek to understand. When one sees surveys showing that American kids do worse at math and science then their contemporaries around the world, this sort of thing is the reason why.
Evolution threatens Christianity as much as gravity does.
