Charles Blow in the NY Times:
America has a gauzy, romanticized version of its history that is largely fiction. According to that mythology, America rose to greatness by sheer ruggedness, ingenuity and hard work. It ignores or sidelines the tremendous human suffering of African slaves that fueled that financial growth, and the blood spilled and dubious treaties signed with Native Americans that fueled its geographic growth. It ignores that the prosperity of some Americans always hinged on the oppression of other Americans.
Much of America’s past is the story of white people benefiting from a system that white people designed and maintained, which increased their chances of success as it suppressed those same chances in other groups. Those systems persist to this day in some disturbing ways, but the current, vociferous naming and challenging of those systems, the placing of the lamp of truth near the seesaw of privilege and oppression, has provoked a profound sense of discomfort and even anger.
