Points of view are often different.  Thank God.  Education (and democracy) relies on the free exchange of these points of view.  Therefore, controversy is expected; it is a given.  To keep a student away from controversy is to deny education.  In this way it is also a fetter on good citizenship.  The onus should remain on parents, NOT teachers, to censor their child's education.  This ammendment should be struck down.  In leiu, please consider giving teachers a pay raise.
