He also used force of arms to conquer the States which should have had the right to leave the union.

Uh, no. There is no proscribed method for leaving the Union because it doesn't happen: the entire point is that once you join, you can't leave. This was understood well before the Civil War as various territories applied for statehood.

The conception and advocation of secession is the single worst contribution Thomas Jefferson has made to this country.

He above all was responsible for converting our sovereign States into vassals of the federal government.

No, Lincoln was responsible for preserving the union, nothing more. The federal government did not become the "do what we want or we'll take away funding for your programs" machine it is today until FDR came along.

When certain states joined the union they did so only with the understanding that they could leave the union if things didn't work out. The ratification documents of the states of Virginia and New York specifically state that those States reserved the right to secede. Virginia chose to exercise this right, and Lincoln subsequently stormed the Virgina State House with Federal Jackboots and arrested the legislature.

Abe's actions certainly fit the definition of 'tyrannical'. The war was about States Rights and international commerce, and had little or nothing to do with slavery.
