Honestly this video did not surprise me one bit. At this young age, children might not know the difference from right and wrong and need to be taught it. Children respect and listen to the adults in their life so much, and their teacher is one adult that impacts them greatly. If the teacher was saying to treat others a certain way, they will most likely do it because it is someone they trust. I think this was a great exercise for the kids to teach them the importance of discrimination at a level they could truly understand.
