Gotta fall in with the "bad idea" crowd....
I don't recall evolution coming up in any of my Religious Studies classes.
Even if it did, it's not just a question of "equal time." Intelligent design is not science, it's faith. I have no problem with religious issues being broached in school, but it shouldn't happen in a science class. Social Studies, maybe. Better yet, a religious studies elective that acknowledges Christianity as one of many.
