G.Y.: This “intentional ignorance” regarding inconvenient truths about the suffering of African- Americans can also be used to frame the genocide of Native Americans. It was 18th century Swedish taxonomist Carolus Linnaeus who argued that Native Americans were governed by traits such as being “prone to anger,” a convenient myth for justifying the need for Native Americans to be “civilized” by whites. So, there are myths here as well. How does North America’s “amnesia” contribute to forms of racism directed uniquely toward Native Americans in our present moment and to their continual genocide?

N.C.: The useful myths began early on, and continue to the present. One of the first myths was formally established right after the King of England granted a Charter to the Massachusetts Bay Colony in 1629, declaring that conversion of the Indians to Christianity is “the principal end of this plantation.” The colonists at once created the Great Seal of the Colony, which depicts an Indian holding a spear pointing downward in a sign of peace, with a scroll coming from his mouth pleading with the colonists to “Come over and help us.” This may have been the first case of “humanitarian intervention” — and, curiously, it turned out like so many others.

Years later Supreme Court Justice Joseph Story mused about “the wisdom of Providence” that caused the natives to disappear like “the withered leaves of autumn” even though the colonists had “constantly respected” them. Needless to say, the colonists who did not choose “intentional ignorance” knew much better, and the most knowledgeable, like Gen. Henry Knox, the first secretary of war of the United States, described “the utter extirpation of all the Indians in most populous parts of the Union [by means] more destructive to the Indian natives than the conduct of the conquerors of Mexico and Peru.”

Knox went on to warn that “a future historian may mark the causes of this destruction of the human race in sable colors.” There were a few — very few — who did so, like the heroic Helen Jackson, who in 1880 provided a detailed account of that “sad revelation of broken faith, of violated treaties, and of inhuman acts of violence [that] will bring a flush of shame to the cheeks of those who love their country.” Jackson’s important book barely sold. She was neglected and dismissed in favor of the version presented by Theodore Roosevelt, who explained that “The expansion of the peoples of white, or European, blood during the past four centuries…has been fraught with lasting benefit to most of the peoples already dwelling in the lands over which the expansion took place,” notably those who had been “extirpated” or expelled to destitution and misery.

The national poet, Walt Whitman, captured the general understanding when he wrote that “The nigger, like the Injun, will be eliminated; it is the law of the races, history… A superior grade of rats come and then all the minor rats are cleared out.” It wasn’t until the 1960s that the scale of the atrocities and their character began to enter even scholarship, and to some extent popular consciousness, though there is a long way to go.
