It is not about the belief itself, it is about the reasons one has for the belief. There are good reasons and there are bad reasons. With religion, it always comes down to a matter of faith. Religion is the only area of our discourse where faith is a good reason, with anything else people talk or debate about, evidence is the winning driver.
This, BPV, is why ID is not taught in schools....at least not science classes. If it is to be brought up, it belongs in a philosophy, sociology, or theology class. It simply doesn't fit the criteria to be considered legitimate science. If it is, then we should make it free for students to study alchemy and astrology as real science.
