What's the big deal with MLK?

What's the big deal with Martin Luther King, Jr.? A lot. The man was smart, as seen in his letter from Birmingham jail. He wrote it in the dark of jail, with nothing inspiring him except the reason of why he was in jail in the first place. In the letter, the organization, spelling, and grammar are impeccable; this essentially is his rough draft. He uses words that only the high class knew, and he wasn't sitting around with a dictionary. He also pulls history from all sorts of places to make his points, without a set of encyclopedias with him. Why is he great? He had an answer for everything he did. It's more than most people have including the president. He explains things that others could not satisfactorily explain. He's amazingly literate for someone who wasn't allowed to get the top education. His conviction and passion were unparalleled by most anybody, and he expressed himself in terms that you could feel his passion and know exactly where he was coming from.
