The enforcement of this regulation is a disservice to to all students and prevents them from receiving a well-rounded and factual presentation of the world as it is today.  Forcing this regulation on school administrators and teachers will only serve to take time away from actual instruction.

Trying to keep students in a bubble that does not reflect real world and its population does not prepare them for life they will experience once out of the shelter of parents.  The banning of books did not serve anyone in the past and certainly will not serve anyone now.
