This is an accurate depiction of teaching American history in that it shows the evils of slavery and the killing of native Americans as the country expanded at their expense. Being done in the 1930’s adds another dimension to this great art work. Removing this because of mid characterization of the intention for political purposes is not right. Do not destroy this please.
The Murals were created to express the complexity of history by showing the dark side of the historic heroes. This is hard to take, but it is an important part of this art, and an important experience for students. The mural does not glorify slavery or oppression. quite the contrary.
