I see that you've launched yet another divisive post, one that I find to be personally insulting, to be honest.
Okay, tell me the "principles" over which you believe the Civil War was fought. Tell me what you mean by "apologists for those who lost" and just how many of those people do you believe are actually in existence today.
To be brutally honest, simply regurgitating what you were taught in high school and/or college from broad generic historical text books tells me nothing. In fact, from your commentary, I can tell that you know NOTHING about the economics of the South or why so many dirt-poor Southerners who went off to war whose family-lines had NEVER owned slaves.
And how about the Northern states that allowed slavery? Pennsylvania allowed slavery until 1850, Minnesota until 1858, Iowa until 1846, and Wisconsin until 1848. Here are some maps:

Now let's talk about the Emancipation Proclamation of 1862. You do know that Lincoln freed only those slaves still living in areas under Confederate rule, don't you? All of the slaves still living in Northern state, border states, AND those areas of the South already occupied by the Union were NOT freed. Repeat...NOT freed. Why do you think that was the case? What great "principles" were being exhibited by Lincoln with that proclamation? Could one think of the proclamation as just another political tool used to unsettle the Confederacy?
Additionally, tell me what "principles" were involved in the decision to wage what amounts to total war on the South. You do understand that when the war was over, the South was left with very little in the way of crops and livestock. Very few historians, if any, have touched on the number of babies and young children that starved to death in the South following the war. Too bad that you didn't visit any Southern cemeteries while you were visiting all of those battlefields in the South...maybe your education could have been broadened by seeing the number of young people that died within a couple of years of the end of the war.
My comment about "unity" was in terms of ALL Democrats standing together to rid ourselves of the NeoCon Evil Empire. I can certainly see that such idealistic thinking was wasted on such a "principiled" person like yourself.
As far as another Civil War taking place, never has that threat been stronger than it is today. But I certainly didn't need you to tell me that...I've been watching this one grow on the horizon since JFK was killed in 1963.
