You asked me a speculative question and I gave you an educated guess for an answer. Nobody can do better than that.
I take people as they come [...] But to the poltroon’s of the Old South, I’m sorry, they sought to keep an entire race enslaved for money.
If you want to talk BS, you should remember the phrase “Everything before the word ‘but’ is BS.” As you wisely point out (then unwisely negate), we don’t know exactly what someone else is going through. Most of the Southern whites owned no slaves, largely because they were too poor to own any even if they wanted them. Many fought because they were loyal citizens of their State as well as loyal citizens of the nation they perceived was betraying them (Lee was a loyal son of Virginia first, so he rejected an officer commission in the Union Army at the beginning of the war).
And yes, all have gone to their judgment already... but I won’t presume to know how it went for any or all of them.
This is the whole problem (and why you are wrong). You’re not wrong to say that maintaining a slavery-driven economy was the single primary motivation to go to war, and that such a motive is an evil one... but that alone is a half-truth (that is to say, a cleverly-dressed falsehood). The full set of motivations are far more complex than this and draw in other political motives pertaining to the rights of states in addition to any multitude of personal motives among the individual Confederate soldiers, thus your explanation is grossly oversimplified.
If you are so convinced that you are right that slavery is the only issue, why not go to the logical conclusion and condemn the Founding Fathers for creating such a wretched compromise in framing the Constitution in the first place—declaring the African slave as 3/5 of a man for the sake of counting population, but for the sake of his rights as a citizen counting him as no man at all? And then when you do, I will be curious to see if you condemn the Fathers if the slave states more for desiring the slaves be pawns to gain a greater apportionment of representation in the House and Electoral College... or the Fathers of the free states more for initially not wishing to count the slaves at all before finally using the slaves as pawns in settling on the compromise to ensure the Constitution would be ratified.
