This was deeply painful to read. Deeply painful. Obviously you have neither taken Advanced Placement US History, Advanced Placement World History, collegiate US History, or really read any of the many different tomes at the library on the Civil War and that time period. The entirety of this was flat-out wrong.
Lincoln argued for limiting it during the Presidency campaign, but it did not match his personal beliefs. He was a complex person, with much internal conflict on his views of slavery. He has said he would do away with it if he could. In the middle of the war, by now public opinion had turned on its head (specifically, the North's army, where due to working with black regiments composed of runaway slaves they had freed, among other instances which increased anti-slavery sentiment), where the North had switched to fighting for the sake of ridding slavery in the South.
A civil war is an internal conflict between citizens of the same country. That's it. Don't try to complicate it. It was the Union against Confederates, both of whom were/are citizens of the same country. It was a civil war. A war of secession is, by definition, a civil war.
And the whole thing about "the North violating their state rights" was one of the greatest victories of the South: getting that drivel into high-school textbooks. You won't see that, unless you are really deep down South (and even then, it's not normal), in your college textbooks because it's completely false. You literally only have to read the secessionist statements every one of the states leaving made, and it's clear as day: they did it to keep their slaves and to do it to the level of control the culture felt they needed to exact. They definitely mention states' rights. Everything starts with a kernel of truth. In fact, for the SC secessionist statement, that is the first half of the document, where they set up context. Do you know what evidence they offered for violating their rights? The laws that institutionalized slavery. If you want to read the
whole thing and actually analyze it without being biased, here's the link:

And the whole debacle in Kansas came from slavery too.
Educate yourself. Please.
