Yea, the only thing an intelligent person has to do is read the ******* letters the southern states (confederacy) wrote explaining why they were seceding. Then read the speeches from the president and vice president of the confederacy to know why they were going to war.
Well if you read Davis's inaugural address he states, "our true policy is peace, and the freest trade which our necessities will permit." So it's not quite that simple.

yeah, it is
The new Constitution has put at rest forever all the agitating questions relating to our
peculiar institutions—African slavery as it exists among us—
the proper status of the negro in our form of civilization. This was the immediate cause of the late rupture and present revolution. Jefferson, in his forecast, had anticipated this, as the "rock upon which the old Union would split." He was right. What was conjecture with him, is now a realized fact. But whether he fully comprehended the great truth upon which that rock stood and stands, may be doubted.
The prevailing ideas entertained by him and most of the leading statesmen at the time of the formation of the old Constitution were, that the enslavement of the African was in violation of the laws of nature; that it was wrong in principle, socially, morally and politically. It was an evil they knew not well how to deal with; but the general opinion of the men of that day was, that, somehow or other, in the order of Providence, the institution would be evanescent and pass away...
Those ideas, however, were fundamentally wrong. They rested upon the assumption of the equality of races. This was an error. It was a sandy foundation, and the idea of a Government built upon it—when the "storm came and the wind blew, it fell."
Our new government is founded upon exactly the opposite ideas;
its foundations are laid, its cornerstone rests, upon the great truth that the negro is not equal to the white man; that
slavery, subordination to the superior race, is his natural and normal condition. This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth. This truth has been slow in the process of its development, like all other truths in the various departments of science.

i'd also suggest you familiarize yourself with the declarations of causes of the seceding states.
they're very honest about the reason they seceded- it was to keep slaves
