““To have a museum chronicling the great crime that was African slavery in the United States of America would be to acknowledge that the evil was here . Americans prefer to picture the evil that was there , and from which the United States-a unique nation, one without any certifiably wicked leaders throughout its entire history-is exempt. That this country, like every other country, has its tragic past does not sit well with the founding, and still all-powerful belief in American exceptionalism.””
