Though it was necessary to enact civil rights legislation, you cannot erase four hundred years of race-based oppression by passing a few laws. From the earliest years of slavery in the 1600s, through the legal end of Jim Crow in 1954, and in the numerous and varied ways in which racism is still enacted in law and culture today, the United States has had more than 300 years of race-based discrimination. A few short decades of legal freedom have not corrected the damage done by centuries of racism.
