That is what Dr. King did -- not march, not give good speeches. He crisscrossed the south organizing people, helping them not be afraid, and encouraging them, like Gandhi did in India, to take the beating that they had been trying to avoid all their lives.Once the beating was over, we were free.
Dr. King had many other goals, many other more transcendent, non-racial, policy goals, goals that apply to white people too, like ending poverty, reducing the war like aspects of our foreign policy, promoting the New Deal goal of universal employment, and so on. But his main accomplishment was ending 200 years of racial terrorism, by getting black people to confront their fears. So please don't tell me that Martin Luther King's dream has not been achieved, unless you knew what racial terrorism was like back then and can make a convincing case you still feel it today. If you did not go through that transition, you're not qualified to say that the dream was not accomplished.
If we do it all together, we'll be OK.
