Good points made over at American Thinker:
Keeping people on the boil makes for very powerful group politics, which is why demagogues and tyrannical regimes do it all over the world. But there is an awful cost when individuals or groups remain in turmoil over wrongs that lie in the past....
What the Left has done to black people in the last fifty years is a kind of emotional abuse -- a constant, obsessional reliving of the traumatic past. Fifty years after the Civil Rights Acts, Democrat politicians, professors and preachers are still intent on rubbing salt into those old, painful wounds. It has now become institutionalized. Reliving the past is a major reason for Black Studies Departments all over the country, just as Women's Studies are designed to perpetuate an everlasting cry of pain and rage about the fate of women throughout history. Those constant rehearsals of reasons for rage and resentment do not to help people; they just exploit their pain for political gain.
