Revisionism always loses, but it does so at great and tedious cost to the victor.
Ask a revisionist what caused secession. He’ll tell you something vague or plainly incorrect – anything but the truth. Argue about it for an hour and he will have literally no choice but to admit that lo! slavery was the explicit cause of secession. Every other avenue he tried will have been snuffed out by his own inability to produce evidence.
Next he will claim that the North was no worse on the issue of slavery than the South. This will go on for a while until it is with great and frustrated reluctance accepted that “the North was nowhere remotely near as bad as the South” (which should be obvious given that the latter seceded explicitly because of anti-slavery sentiment emanating from and headquartered in the former [anti-slavery sentiment that, by the way, was translated by Northern lawmakers into actual laws in the period leading up to the war]) =/= “the North was perfect and totally harbored no racists and fought the war because #blacklivesmatter[/i].”
And on and on it will go. Now we have arrived at the “winners write the books” line. What does this mean? Nothing. It would mean something if it were attended by some evidence that the Union victors fabricated the historical facts under discussion, but nobody here believes that, e.g., the secession declarations were propagandist hoaxes perpetrated by some Orwellian committee of falsifiers. From there it is downright mechanical: nobody, save for a moral relativist, believes that the existential cause of the CSA is anything but morally reprehensible. Again, “winners write the books” doesn’t mean anything here. We’re not working with suspect evidence.
This has, in other words, been largely the same old song for me (well, almost the same old song: I hadn’t heard the screeching lunacy that you get when you play it backwards). However, TB and DD made good points, and I think I’ll adjust my position to maintain that CSA leaders should not be celebrated (with public money/property) in their capacities as CSA leaders. Thus the moral filth that is and always has been (remember: we aren’t moral relativists) the CSA cause, meaning, legacy gets what it deserves, but we can still honor the few complicated men who redeemed themselves while refusing to do something so stupid as to celebrate them qua Confederates.
