Throughout his participation in the civil rights movement, King was criticized by many groups. This included opposition by more militant blacks such as Nation of Islam member Malcolm X .  Stokely Carmichael was a separatist and disagreed with King's plea for racial integration because he considered it an insult to a uniquely African-American culture.  Omali Yeshitela urged Africans to remember the history of violent European colonization and how power was not secured by Europeans through integration, but by violence and force. 
So let freedom ring from the prodigious hilltops of New Hampshire!
Let freedom ring from the mighty mountains of New York!
Let freedom ring from the heightening Alleghenies of Pennsylvania!
Let freedom ring from the snowcapped Rockies of Colorado!
Let freedom ring from the curvaceous peaks of California!
But not only that; let freedom ring from Stone Mountain of Georgia!
Let freedom ring from Lookout Mountain of Tennessee!
Let freedom ring from every hill and every molehill of Mississippi!
From every mountainside, let freedom ring!
