Just asking out loud here: Since Kelly was born and raised in South Carolina, went to college at Duke, in North Carolina, might it be possible Kelly, in her comments on lynching Tiger, be a closet racist?  By that I mean one who grew up in a culture of white southern golf eltists who play golf at courses where blacks cannot join or play.  I bet if her family goes to church, it's an all white church congregation. She probably grew up hearing (and possibly influenced) by comments most southern whites use among themselves(I have relatives myself who talk this way, so I know) as: calling black males by the name "boy"; using the "N" word; defaming the looks of blacks (afros, noses, lips, etc.); etc.
Most white Americans do not realize that blacks were lynched in the South as recently as 1970 if not later (in Mississippi).  Once in a while you will hear comments "slip out" of the mouths of whites that simply reveal what's on the inside of their minds that normally that they would never say outloud in public.  But the thoughts, language, and bigotry are still there simmering near the surface.  Just look at how many notables have been caught this past couple of years using terms or comments that "shock" most people.  Believe me, coming from a family history of southern racist bigots (and slave holders)that I am sorely ashamed of, racism is still alive and well in the U.S.  It's mostly clandestine (undercover), but it is still there and shows its ugly head on occasion when least expected.
