Interesting. Any sixth grader in my culture would grasp the impact and the message of this story quite easily. I come from an Orthodox Jewish background where children are taught about the Holocaust in great detail and it is discussed often probably starting in fourth or fifth grade. Many kids in the community who are that age have great grandparents who were Holocaust survivors. We all have a deep understanding of how horrible people can be to their fellow human beings. What we do not have is any sort of collective guilt over the terrible treatment of black people in this country’s history.
