We've deliberately dismembered him through manipulation of his memory. And those of us who have failed to see his radical challenge, in deference to a vision of King that is one of a universalist, that everybody can attach to — which was true, of course — but that wasn't the full story.
The full story is: Here was a man who made most Americans, black and white, uncomfortable. Because he demanded a serious commitment to social inequity, and to remove social injustice where he found it. That's why he continued to say, "Injustice anywhere is a threat to justice everywhere."
Here is an interesting article from Salon's interview with Michael Eric Dyson about how we misremember MLK and his message. Lately we've seen entities who would have been on the opposing side of Dr. Martin Luther King Jr. during the 60s (codeword for the GOP), hijack his message for their own political propaganda. We must remember what Dr. King truly stood for, in order to prevent entities like the GOP from revising the legacy of MLK for their own agendas.
