That article is so wrong it is hard to know where to start.
The author doesn't appear to have any credentials as an expert on the Civil War.:

"A well-written article. Too bad the author knows almost nothing about the cause of the Civil War. Ms. Patel, please search the following declarations of secession for mentions of the word "tariff", "duty", or "tax" and see how many matches you get:"

"It used to be much more difficult to refute nonsense like this article, but the Internet makes it OH SO EASY.""Was the Morrill Tariff the Reason Southern States Seceded? No, the secession crisis really began in late 1860, and was sparked by the election of Abraham Lincoln. It is true that mentions of the "Morrill bill," as the tariff was known before it became law, appeared during the secession convention in Georgia in November 1860. But mentions of the proposed tariff law were a peripheral issue to the much larger issue of slavery and the election of Lincoln."
http://history1800s.about.com/od/civilwar/f/morill-tariff-civil-war.htmLincoln's anti slavery views were well known as result of the Lincoln/Douglas debates and Lincoln's Coopers Union speech. Lincoln was elected on an anti-slavery Republican platform. Lincoln was elected President of the whole country, not just the North. The South would not abide by the results of the presidential election, and engaged in armed revolt. The North fought to preserve the Union and representative democracy. The South fought to perpetuate it's significant investment in "property" in the form of human slaves.
I don't have any credentials as an expert on the Civil War either, which is why I provide cites for my declarations:

http://showcase.netins.net/web/creative/lincoln/speeches/last.htm"For the first time in a public setting, Lincoln expressed his support for black suffrage. This statement incensed John Wilkes Booth, a member of the audience, who vowed, "That is the last speech he will make." A white supremacist and Confederate activist, Booth made good on his threat three days later."
"Libertarian historian and economist Thomas DiLorenzo asserts that the tariff was the primary cause of the Civil War. Nearly all Civil War historians disagree. Allan Nevins and James M. McPherson downplay the significance of the tariff dispute, arguing that it was peripheral to the issue of slavery. They note that slavery dominated the secessionist declarations, speeches, and pamphlets. Nevins also points to the argument of Alexander Stephens, who disputed Toombs' claims about the severity of the Morrill tariff. Though initially a unionist, Stephens would later cite slavery as the "cornerstone" reason behind his support of the secessionist cause."
