Anything that is not history, math, science, biology, etc.
In the 6-7-8th grade (at least here in California) there are a number of assigned books and lessons that teach (as best as I can describe it) "empathy". Which is great... but some of the books had a very strong viewpoint one way or the other that was persuasive but not always well rounded.
Personally when I was that age the "empathy" lessons were way better in middle school. They lasted a semester or two, we watched a movie called "The Lottery" where a village picked from a lottery to stone one person (I can't remember why, a good harvest I am not sure) but a mother was chosen and it was so ingrained in the children to stone the person her own children looked forward to the stoning and the mother tried to get the children to think "hey this is my own mother". Another lesson was the poem about when you let bad things happen to others, when bad things happen to you there will be no one left to speak up on your behalf (can't remember the title), and the third one was on cultural understanding if someone hundreds of years from now examines your house and get what is inside of it "wrong" (like assuming the toilet is a communication device you yell into, or toothbrushes (with hooks) were ear-rings) not to think badly of those people (and as such you may make the same mistakes when look at the lives of people you're not familiar with).
