The CRM did much harm.  Ironically, Integration contributed to the disintregration of the black nuclear family (MLK selfishly ignored the writing on the wall in the form of the Moynihan Prophecy).

Also, because of integration, the black community abandonmened the economic base developed out of necessity during segregation.  Forty years after the fiasco, it has become apparent that the CRM is a substandard house that was built on a foundation of sand (Matthew 7:24-27).
