the REVISIONIST HISTORIOGRAPHERS, out of the most extreme, leftist,elitist fringe of poison-ivy league academia, came up with the "slavery was all" theory in about 1965, as a COVERUP for the THOUSANDS of damnyankee atrocities committed by the bluebelly army against CIVILIANS & HELPLESS CSA POWs.
IF they could convince the populus that the WBTS was a crusade against slavery (and they KNEW it was NOT!), then the atrocities might be seen as less hideous!
free the southland NOW,sw
Best of luck.
