I feel like my child's teachers have enough to do without having to spend time labeling everything they teach as sensitive or not.  Please let them focus on teaching and not having to spend so much time on busy work.  I feel like the parents I know are happy with what is being taught and that is why they send their children to public school.  If a parent is concerned about class content, then let them talk with the teacher as individuals and let that parent and teacher work something out as opposed to making a blanket amendment that will effect everyone wether they needed it or not.
