As I mentioned, in April 1861 blacks did indeed volunteer to fight U.S. troops, but none were accepted. Frederick Douglass did say what he did early in the war, but he was misinformed. Anecdotes here and there (and a diary mentioning black rebels fighting off a regiment (1000 or so soldiers, a week before Appomattox -- I don't think so) don not amount to much. Today's neo-Confederates cling to the myth of blacks fighting for the Confederacy because they do not want to admit what the Confederates themselves say they fought for. Just look at the rebel states' declarations of secession and the pro-secession speeches in the secession conventions. It's all about slavery and how they had to fight to keep blacks enchained -- nary a word about the tariff or states rights or anything else.
As for being manacled by rebels and marched south into slavery, you wouldn't be LOL if it happened to you.
Like I said, read widely, and with an open mind. Get beyond the textbooks written for the government schools, and the PC textbooks. Read letters from the era, and ask yourself if the popular, PC, North, good/South, bad version of the conflict could POSSIBLY be the truth, in the light of those letters from the people who lived it.
The North has not yet won culturally, but they have made great headway. They still use Blacks as pawns, and pit Blacks and Whites against each other to wield power. Like many Southerners until Reagan, you have not noticed that the parties have switched philosophies (remember Thomas Jefferson was a Democrat, too). The GOP seems to be returning to its old self, though, unfortunately, and the Dems are, well, we all know what they are.
As to LOLs, bloody Bill Anderson obviously wasn't laughing about things going on then, either, nor were any Southerners, Black or White. Look into it all, if you dare - you'll be surprised.
