the NPS, just 2 years ago, attempted UN-sucessfully to block the men from wearing rebel gray, to "assure that no persons MIGHT (emphasis mine.)be offended by seeing any such persons" at a memorial ceremony in Gettysburg,PA for ALL the veterans who died in the war.
btw,during TWBTS, there were 3 ALL-black CSA units, with black commissioned OFFICERS leading them. the units were old state militia units, which dated to the War of 1812 period.
by 1863, ALL the large CSA military formations were DE-segregated by race/ethnic group/religion.

I am pleased that my hopeful prediction was over a 100 years too late.
