My son is getting bullied at school and I think it is teachers fault.

For the last few weeks, my son has been getting relentlessly bullied at school. I have been to talk to his principle twice but nothing has stopped it.It all started after a class project about slavery. His US history class was divided into slavery advocates, and abolitionists. They were given a week to research and present a case for or against slavery.My son was chosen on the pro slavery camp. Like every assignment he took this one seriously. He worked very hard, he argued his case historically like he was actually a slave owner of the time.Because of his hard work, he was the only person in his class to receive an A+ on the assignment.Afterwards, kids in his class started calling him racist, and KKK. It spread to others in his middle school, and he even got jumped by a couple of other boys.I think this assignment was reckless in today's political climate. It was also reckless to put on of the only little white kids in class on the pro slavery team, random or not.My husband and I are thinking of transferring him to a different school because of this. What should we do?Edit: I dont think it matters, but I have the notes from his presentation/debate, so if anyone wants to know what he said I can tell you. via /r/Parenting http://ift.tt/2gZFkr6
