The Sons of Confederate Veterans- What racist deeds have they perpetrated? - Why are they vilified? 

They tend the graves of Confederate dead and place flags on Memorial Day. They contributed to the restoration of the home of Jefferson Davis, damaged by Hurricane Katrina. They publish the Confederate Veteran, a magazine that relates stories of the ancestors they love to remember. They join environmentalists in fighting to preserve Civil War battlefields. They do re-enactments of Civil War battles with men and boys whose ancestors fought for the Union. And they defend the monuments to their ancestors and the flag under which they fought. 

Why are they vilified? 

Because they are Southern white Christian men—none of whom defends slavery, but all of whom are defiantly proud of the South, its ancient faith and their forefathers who fell in the Lost Cause.
