Correct, but does not have any relevance to your original statement.
Most of the wars in human history have several reasons that come to a head in the form of military aggression. The Civil War was no different. HOWEVER, this was your quote:
This is factually incorrect. All you have to do is read the articles of secession filed by each state to know that this is fact.
Which is another way of explaining that the Civil War was fought primarily to preserve slavery in the south. 
Because of the movement to stop slavery (the abolitionist movement that was primarily based in the north) southerners concluded that all or most northerners were against them and wanted to destroy their way of life. Southerners developed the illusion that all northerners were against them and it united the southern states.
Wrong. What in actuality the abolitionists were arguing for was to give enslaved Africans full citizenship, which would include the right to vote. Given that slaves actually outnumbered whites in many southern states, southern slave owners knew Africans would vote to abolish the despicable practice, thereby gaining their freedom and whitey could kiss his wealth and free labor goodbye.
Where are you from, McNuts?
LOL again states rights was the issue
as for the legislation you said i was wrong about
The Tariff of 1828, was a high protective tariff or tax on imports passed by Congress in 1828. It was labeled the "Tariff of Abominations"[65] by its southern detractors because of its effect on the Southern economy. The 1828 tariff was repealed after strong protests and threats of nullification by South Carolina.
The Democrats in Congress, controlled by Southerners, wrote the tariff laws in the 1830s, 1840s, and 1850s, and kept reducing rates, so that the 1857 rates were the lowest since 1816. The South had no complaints but the low rates angered Northern industrialists and factory workers, especially in Pennsylvania, who demanded protection for their growing iron industry. The Whigs and Republicans favored high tariffs to stimulate industrial growth, and Republicans called for an increase in tariffs in the 1860 election. The increases were finally enacted in 1861 after Southerners resigned their seats in Congress.[66][67]
Historians in recent decades have minimized the tariff issue, noting that few people in 1860-61 said it was of central importance to them. Some secessionist documents do mention the tariff issue, though not nearly as often as the preservation of slavery. However, a few libertarian economists place more importance on the tariff issue.[68]
Antislavery forces in the North identified the "Slave Power" as a direct threat to republican values. They argued that rich slave owners were using political power to take control of the Presidency, Congress and the Supreme Court, thus threatening the rights of the citizens of the North.[63]
"Free soil" was a Northern demand that the new lands opening up in the west be available to independent yeoman farmers and not be bought out by rich slave owners who would buy up the best land and work it with slaves, forcing the white farmers onto marginal lands. This was the basis of the Free Soil Party of 1848, and a main theme of the Republican Party.[64]
slavery was how the issue manifested itself...
