Your theories are full of crap. They don’t survive the reality test.
Pretty sure there was a lot more than just New York newspapers in there, but if there isn't, let me assure you there are Boston and Chicago newspapers that make the same points as well.
Hear that FLT-Bird? He doesn't like New York (the place making the most profits from international trade) because it is too pro-slavery. He wants to see what Newspapers in other states thought. Can you oblige him?
... and Charles Dickens who hated everything about the United States.
You have evidence Charles Dickens hated the United States? From what I have read of his "Notes on America", he very much liked the United States. He spent a year touring the country, giving speeches and whatnot.
He was a staunch abolitionists and hated slavery, and during his tour of the South he urged slaveowners to give it up!
So you don't like what he says unless it agrees with you?
So if the Union side didn’t care one whit about slavery, why were the slaves freed?
Don't add more complexity to something you already don't understand. We'll get to that topic later. First you got to grasp the economics of the situation, then later we can get into the politics of the situation.
If they just wanted to make money off the South, why did they nearly destroy it?
We'll get to that later.
If the North were such mean, heartless bastards, why didn’t they hang Davis, Lee and every other high ranking Confederate?
We'll get to that later. Clearly you haven't read what Supreme Court Chief Justice Salmon P. Chase said on the matter.
You have a lot to learn before you can competently discuss this issue.
