My viewpoint, in telling the history of the United States, is different: that we must not accept the memory of states as our own. Nations are not communities and never have been. The history of any country, presented as the history of a family, conceals fierce conflicts of interests (sometimes exploding, most often repressed) between conquerors and conquered, masters and slaves, capitalists and workers, dominators and dominated in race and sex. And in such a world of conflict, a world of victims and executioners, it is the job of thinking people, as Albert Camus suggested, not to be on the side of the executioners.
…My point is not to grieve for the victims and denounce the executioners. Those tears, that anger, cast into the past, deplete our moral energy for the present. And the lines are not always clear. In the long run, the oppressor is also a victim. In the short run (and so far, human history has consisted only of short runs), the victims, themselves desperate and tainted with the culture that oppresses them, turn on other victims.
