Why does the 4th grade mission project requirement continue when Indians were tortured and killed there?

Not many people seem to know the truth, but ask any native american and they will tell you. The government does not want to tell you how terribly they wiped out the Indians. Its not all by disease. It was by starvation, beating, hanging, dehydration, they even massacred entire tribes at a time. No one talks about it. I understand not coming to full agreement, but can we please stop glorifying these torture chambers to children? I mean, we can talk about the holocaust, but we can't talk about what our own country did to its native people?
