I seem to remember getting a very centrist version of the Native American Genocide. Crimes committed against the Native Americans by colonists were skimmed over in brief, settlement of land was described as a net positive because the GDP went up and railroads got built, there was a little bit of time spent on the Indian Removal Act and the Trail of Tears, and then it was on to talking about the Mexican-American War and Native Americans never got mentioned again after that.
