Nothing wrong with history, but it just depends on whose telling it, how graphic it is, how detailed it is, thus causing the ratings that should determine age appropriate level's, and the year level to teach it in, otherwise when it comes to student's learning such history at the appropriate time. No one should ban history, but they should always be mindful on how it gets taught, and at what age levels should each subject be taught at. We use to know these things, so what the heck has happened ??
