Oh I agree with you. It's why I want the guidelines on evolution changed to present not just the theory of evolution but the controversy surrounding it and alternative views. Because right now a teacher can't tell the students the whole truth about certain subjects.
But on American History I probably wouldn't have to go outside of the guidelines. I don't think the guidelines yet reflect the atheist revisionist history that our forefathers were not Christians. Or rule out using the actual documents like the Declaration of Independence.
Do you know what the current curriculum calls for in your school district?
