Genocide

Dear (pincipal of high school),
I am writing to you in part of all those who are on my side. History books all over the state are being edited and some even banned from most school. Our question is why? Why is it that our history is kept a secret from us. I know i am not the only one who is against this. We believe that times like when the Rape of Nanking, and genocide acts in other places of the world like Rwanda for example, should be taught to us. Why is it that we are not allowed to learn about that through our textbooks? Us, as americans should know what has happened and what is happening in the world around us, not only so we know what has happened and to be prepared just in case of a repeat but also so we make sure we prevent it from happening again. For example, lets say one of those event come up and hit us out of nowhere, well since we did not learn on what occured and how it was ended we won't know what to do. Our leaders and big people may know what has happened but we are next to fill out their spots and we should be well informed so we learn from their mistakes.
