Biology does not make sense without evolution. Other than evolution, here is nothing to tie it together. If you remove evolution from education, you remove so much that biology becomes pointless, inaccurate, and dangerous. The theory of evolution is a sound scientific theory just like the laws of thermodynamics or the theory of gravity, and because of its utility and its central focus in biology, it should be taught to all high school students.
Creationism should be debunked in biology classes. It is the duty of schools to exterminate the type of ignorance that creationism so perfectly exemplifies. Creationism should not be taught as an equal to evolution, because it has no scientific background and starts from the assumption that the first couple pages of an ancient book are literally true, when no evidence exists to support that claim. It is not science because it was not gathered through the scientific method or anything even resembling a scientific process, rather, it is an article of faith. There isn't enough to it to make a class, and money from taxes should not be spent educating people in what is obviously no more than a facet of fundamentalist Christianity.
The idea that neither should be taught will only allow creationism to become even more widespread. You don't need to take a class on creationism to understand everything creationists want you to know about it, you simply have to take it on faith without asking difficult questions.
I don't see why you think controversial topics should be left out of public education. Some people deny that the holocaust ever happened. Should we leave that out of history classes?
