There have always been individual truths to support every generalized racist lie. It is true that some Black opportunists sought favor if slavery persisted by supporting the Confederate cause. It is true that some starving free Blacks supported the rebels for lifesaving provisions. It is true that Black racists who believed that Black people were better off enslaved sometimes voluntarily aided the Confederacy. The number of voluntary Black Confederates? Probably not many. But no one can say for sure.
