Answer: The true brotherhood of America, of respecting the separateness of others . . . and uniting in effort . . . has been so twisted and distorted.
Governor George Wallace was an American politician and 45th Governor of Alabama. He was famous for his opposition to desegregation and his support for Jim Crow positions.
His sentence "The true brotherhood of America, of respecting the separateness of others . . . and uniting in effort . . . has been so twisted and distorted" shows his political leanings. Wallace is arguing that the separation of different people (in this case black and white) needs to be respected, and that it should not be an obstacle for the unity of the country.
Martin Luther King Jr. would disagree with this position, as it clashes with his dream of all men of all races, nationalities and creeds living together as brothers.
