Michael King (his legal name), had an interesting perspective on the 'Roe Effect' when he accepted the Sanger Award from Planned Parenthood. Of course, he also said that "this is not to suggest that the Negro will solve all his problems through Planned Parenthood." When his candle was prematurely snuffed out, Roe had not yet been decided. It would have been interesting, from an academic standpoint, to hear him speak on that decision. Still, he left a niece to carry his legacy, and though largely ignored, Alveda King has some views which are wonderfully radical in today's society.
Though a great orator, King did have faults. And to deify him in such a way that any mention of his faults immediately, automatically and indelibly brands one a racist does injustice to the civil rights movement of which he was a part. Worse, the re-writing of history to match today's mores and values causes erroneous lessons to be learned with devastating consequences.
Of course, the left and right are both equally culpable. Reagan, a great President to be sure, had flaws, and Washington, a flawed man, was still a great President despite the revisionism endemic in textbooks today.
