"You don't integrate with a sinking ship." This was Malcolm X's curt explanation of why he did not favor integration of blacks with whites in the United States. As the chief spokesman of the Nation of Islam, a Black Muslim organization led by Elijah Muhammad, Malcolm X argued that America was too racist in its institutions and people to offer hope to blacks. The solution proposed by the Nation of Islam was a separate nation for blacks to develop themselves apart from what they considered to be a corrupt white nation destined for divine destruction.
In contrast with Malcolm X's black separatism, Martin Luther King, Jr. offered what he considered "the more excellent way of love and nonviolent protest" as a means of building an integrated community of blacks and whites in America. He rejected what he called "the hatred and despair of the black nationalist," believing that the fate of black Americans was "tied up with America's destiny." Despite the enslavement and segregation of blacks throughout American history, King had faith that "the sacred heritage of our nation and the eternal will of God" could reform white America through the nonviolent Civil Rights Movement.
