I think you are replying to me by mistake. I am not vilifying the motives of the Confederate States. I have long argued that they had a right to leave the Union if they so wished. The Declaration of Independence outlines this as a fundamental human right, and this is a position that I have come to agree with.
The independence minded Brits were never subjected to the ongoing insults that were showered on the Southern States by some agitators during the 1840s & 1850s. But that does not change the right of any people to seek to chart their own destiny--or to regain a former independence.
I've read some of it. Elements in the North absolutely detested the Southerners, and not just because of slavery, though there was plenty of puritan intolerance vented on that.
A lot of people may not notice, but everyone in "flyover country" is still being talked down to by our moral superiors in New York. (and Los Angeles)
Some of those New England purveyors of intolerance against the Southerners were called out by Edgar Allan Poe in some of his literary criticisms. He caught some of the best known Northern writers with gross misstatements of the actual facts involved--clear examples of a vicious fanaticism.
And elements in the South absolutely despised the North. Wealthy Charlestonians certainly felt justified in talking down to New Yorkers. Why don't you do a little reading. Here's as good a place as any to start: Madness Rules the Hour: Charleston, 1860 and the Mania for War.
One of your comedy gems was saying that Chicagoans were elitists who looked down on the South. Chicago had been a tiny village -- pretty much a swamp -- thirty years before. They weren't snobbishly looking down on Richmond or Charleston or New Orleans. It was the other way around.
Another hilarious thing you wrote:
According to the North, Slavery wasn't under any threat, so your claim doesn't even make sense on the face of it.
On the contrary, it's your denial that makes no sense. Republicans said they weren't threatening slavery where it already existed, but the slave owners didn't believe them. They felt that any admission that slavery was wrong or morally questionable weakened their economy and society to the breaking point. For some Southerners the fact that the government wouldn't be in favor the expansion of slave territory was enough of a threat or an insult to justify secession.
