This is not a hoax. At least, not an intentional one. It’s sold by the kind of people like Al Sharpton, who smear the memory of civil rights heroes like Emmitt Till by comparing them to Trayvon Martin.
MLK, Jr = Trayvon? Really, because I don’t remember Dr. King sitting on Bull Connor’s chest and punching him in the face before the cops unleashed the dogs and firehoses.
Speaking as the geekiest white guy east of the Mississippi, I am offended on Dr. King’s behalf. Are you?
