People who willingly fight for the exclusive cause of overthrowing democracy in favor of racist chattel slavery are absolutely burning in hell, should there be such a thing.
I don't believe that's why most southerners fought. Perhaps a factor, but not the driving force.
Were they not convinced that their way of life and culture were under attack, beyond just having superiority over other races. Convinced by the elite that did own slaves and whipped into a frenzy, very much like today's politics against taxation.
Additionally, while they were undoubtedly racist, it is unfortunately the case that most never had the opportunity to not be racist. Their friends were racist, their family were racist, their government was racist, they never knew anything else. Is it fair to condemn someone to hell because they were doing what they were taught is good and just? What seems obvious to us in 2025 is not so cut and dry to a person engulfed in racist culture against their will. And never given a fair opportunity to change.
My point being, saying they were all evil is reductive and shows a lack of empathy and understanding of human nature and undermines the true root causes of racism to hand-waving "oh theyre just evil" rather than getting to the heart of what makes someone hold those beliefs
