If the media had been as sophisticated and as scrutinizing in Martin Luther King's Day, as it is in 2012, there's a good chance that he would have been drug into court for plagairism. He would have also been arrested for soliciting prostitutes, possibly even for physical assault of prostitutes!
King was an American Baptist minister. American Baptists are known for their strong stand against slavery and racism. Yet, from my close-range observations, I can assure you that they are not known for keeping a sexually promiscuous pastor in the pulpit. Certainly, King's reputation among colleagues would have been demolished if what we now know had been known back then.
Yet it is not King's morality that we laud today. It is his courage to put his life on the line, leading the masses to join him in working for the Dream that may not even have been his original words! We celebrate the Power of the Dream that continues guiding people who are working for change in spite of powerful, oppressive regimes. Especially the one that "kept good people in their place" while punishing anyone who dared to challenge the abusive, immoral thinking and behavior in this "land of the free."
The King is dead in the literal sense. Long live the Dream!
