We have to stop letting our schools have such complete control over our children.  The progressives have infiltrated our entire education system.  If a child is offended by our American diversity, let them go to a private school where they will not be offended.  Public schools, paid for by taxpayers, should espouse tolerance and share our different traditions, belief, and holidays.  This is a good teaching and learning experience for children and helps them understand and accept these differences.
