I could have missed it, but I haven't seen anyone on this thread say there were NO black Confederates. You have pointed to some examples of a few. The debate is whether numbers are inflated to unbelievable proportions, and if so why. That's the way I've been reading this debate as an impartial observer, since I really don't care how many there were.
Are you sure that's the debate?
I haven't seen anyone here claim an unbelievable number.
