Is Glenn Beck trying to play the race card for the benefit of his followers while being coy?

Is it mere coincidence that Beck selected the Lincoln Memorial, the venue Dr. Martin Luther King Jr. chose for his 1963 "I have a dream" speech?  The date of August 28 also happens to fall on the forty-seventh anniversary of that historic speech.

Are these both coincidences, as Beck insists, or an insidious way to play to the more radical elements of the right wing fringes?  Anticipating possible trouble, Beck has requested that no signs be brought to his rally.

We recall what happened at the huge Tea Party tax protest rally in Washington.  Congressman John Lewis, a former aide to Martin Luther King, remarked that the reception he and another African American congressman received while seeking to enter the Capitol Building was reminiscent of the South in the sixties, when racists sought to snuff out civil rights efforts by Dr. King.
