Dr. Martin Luther King, champion of the Civil Rigts movement in the 1960s, wants to emphasize that he envisions a US society in which there´s full and true racial equality between the African-Americans and other fellow Americans, particulary with the white majority. He means that there should be brotherhood, that black people are no second-class people in the country, that they have the same rights and the same status others do have. Dr. King wants to see all together as in a close family, not the black person being a distant member, a "brother-in-law."
