If you want the curriculum of the science classroom to be strictly "science", why do you want your belief in the consensus science that perpetuates the "Theory of Evolution" to be part of the curriculum?
You are misusing the word "belief". The ID and Creationists have only their religious beliefs that run their thinking about the subject. Science and the scientific method doesn't work on preconcieved beliefs, that is why it is a theory.
But, it is vastly superior than saying that the Earth is 5000 years old, and that every animal was herded onto an ark and somehow figured out how to swim home and find food and such.
You want to teach creationism and ID, do it in a religion class in a religious school, its your choice not to have your child attend a public school.
Its that simple. If you want to teach your kids that The Flintstones is real, go ahead, just don't use my tax money to do it.
