It's a mistake to put too much credence in much of what Maureen Dowd has to say. However, she hit the nail on the head in today's column for The New York Times
headlined 'Boy, Oh, Boy'.
. . . [South Carolinian GOP wingnut Joe] Wilson's shocking disrespect for the office of the president -- no Democrat ever shouted 'liar' at W. when he was hawking a fake case for war in Iraq -- convinced me: Some people just can't believe a black man is president and will never accept it. . . .
Dowd goes on to say, accurately, that " . . . what I heard was an unspoken word [in Wilson's insane outburst] in the air: 'You lie, boy!'"
PS -- Bro. Joe Wilson, Son of the Confederacy, says he's through apologizing. Old times in S.C. are not forgotten.
