Update: Chris Hedges writes an insightful post today on how Dr. King stated his dream was becoming a nightmare.
"King's words have been appropriated by the people who rejected him in the 1960s," said Professor James Cone, who teaches at Union Theological Seminary in New York and who wrote the book Martin & Malcolm & America. "So by making his birthday a national holiday everybody claims him, even though they opposed him while he was alive. They have frozen King in 1963 with his ‘I Have a Dream' speech. That is the one that can best be manipulated and misinterpreted. King also said, shortly after the Selma march and the riots in Watts, ‘they have turned my dream into a nightmare.'"
