Donald Trump recently snubbed an invitation to address the venerable civil rights group. Bob Dole once did, too, claiming they were trying to "set me up." Right. Because the NAACP has such a long history of incendiary rhetoric. As one of its founders, the great scholar W.E.B. DuBois, never really said, "I'm 'bout to bust a cap on these honkies if they don't give me my freedom."
