Neither you nor I can the a “good guy” in regards to the Civil War since the conflict ended 150 years ago and none of us had a damn thing to do with it.
Nowadays people see the sides in much the same way they see their favorite sports team. They pick a side, and then they defend it. For most people in the nation, they pick the Union side, because everyone likes a winner, they don't want to be thought of as a racist, and they have been taught that the South was completely evil and that the Union was the good guys who provided freedom to an oppressed people.
The people who generally chose the South are the people from that region of the Country, or people descended from people who fought for the South in that conflict. (I am neither)
And then there are people like me, who had no dog in the fight, grew up believing that the North did the right thing and that Lincoln was a great man, and then they are either shown the truth, or stumble upon it themselves, and become aghast at how they had been misled about what happened for so long.
I didn't start at the Civil War. My introduction to politics had nothing at all to do with it. I started out opposing Abortion, worrying about the decline of morals in the public behavior, concerned about the creeping homosexual crap, wondering why the nation couldn't balance it's budget, and so forth.
What I started to notices is that problem after problem kept coming back to the 14th amendment. Abortion? 14th amendment. Denial of prayer in public schools? 14th amendment. Homosexual Marriage? 14th amendment. Anchor babies? 14th amendment. Non Natural born citizen assuming the role of President? 14th amendment!
Time and time again, the problems kept coming back to the 14th amendment, and so I noticed that modern problems were often the consequence of the aftermath of the civil war.
And then my best friend, who is black, has always been obsessed about racial issues, and who also has an obsession about history, and especially the civil war, Told me that Lincoln deliberately started the war, and he did it by outsmarting the Confederates. I didn't believe him, because that's not what I had heard all my life.
He told me what he believed happened, and I just dismissed it for years and years. Eventually I learned that there was some evidentiary support for his claim. Two letters he told me about, did in fact exist, and were real.
Then more pieces started coming out. That map I always post had initially convinced me the war couldn't have been over tariffs because the South wasn't paying the tariffs. The map showed it was obviously the North and especially New York that was paying for all the tariffs.
Then someone posted the numbers regarding which Southern exports earned the European money, and now I realized something was very wrong with what I had been led to believe. If the South was earning the vast bulk of European money, why was all the money ending up in New York?
In other words, I'm someone who originally believed as do you and most other people, who slowly, over time, and after exposure to more information, realized we have been misled, and now I see that the war was really about money and power. "Slavery" was just propaganda meant to pacify the rubes, and justify the carnage, after the fact.
I've seen both sides, and objectivity compels me to say that according to the society and laws in place at that time in history, the South was in the right, and the North was in the wrong.
You don't want to believe it, and neither did I.
