The Theory of Evolution is just like any other scientific theory, and should be taught as such. If you choose to disagree with it, then that's alright--I disagreed with many of my teachers before, and it's acceptable to disagree. The topic of Evolution is often the target of criticism by some religious groups, yet we teach topics such as art history (which encompasses ancient cave art) and geology (which often deals with the earth's age), and nobody's up in arms about those topics.
