I would suggest that you attempt to differentiate between what were known as the 'Fire Eaters', that group of vociferous politicians who represented the rich, landed, slaveholding minority and the work-a-day joe who fought in the ranks of the Confederate Armies. Dean's comments were addressed to the average guy in the South who drives around in a pickup truck, with a gun rack and a Confederate flag. These people are the modern day equivalent of the line troops. As posted earlier, the vast majoity of these folks owned no slaves nor benefitted directly from the slave supported economy. These were the people who gave their lives, fortunes and sacred honor and were completely, utterly devastated in their defeat. The rich, those who stood at the podium of insurrection, continued to be rich (comparatively) after the war. The alleged inferiority of the Black race was an attitude that was pervasive throughout both North and South. The same was said of the Irish, who were treated no better than slaves, had no rights to speak of and worked for only the barest of wages in the most menial and dangerous of jobs. The Army of the Potomac was home to a large contingent of Irish troops. Do you think that freeing Southern slaves was first and foremost in their minds as they did their deadly businees on the battlefield. I think not.
The view that the War was fought to end or prolong slavery as it's dominant motivation is wrong headed and inaccurate. It is, however, politically correct to think in those terms as the arguement serves to lionize the North (and by extension, the Federal government; whose crimes and usurpation of powers not granted under the Constitution during this period are legion), villianize the South, thus making it not only excusable but laudable to visit the sufferings upon it that took place during the War and Reconstruction,
and provide those who currently seek to keep the Black race in economic bondage a 'boogie man' to point to, thus reinforcing the 'culture of victihood' and the Federal nanny state. There was nothing 'moral' about the War, it was a political and economic test of wills. The adoption of the slavery issue as motivation came late in the show and was a political expedient geared toward having abolitionists vote Republican,
keeping Britian and France out of the War and groping desperately for 'moral' justification in the midst of a gross immorality. To try and paint it with the brush of altruistic holiness is absurd, hypocritical and flies in the face of historical fact.
