"Now that Mr. Lincoln is successful, they should be upon our staute [*sic*] book, so long as we remain in the Union. There can no longer be a reasonable doubt, that the gallant State of South Carolina will secede from the Union very soon after her Convention meets. The States of Florida, Alabama and Mississippi will follow in quick succession. While our Convention is in session, we shall probably be surrounded on every side but one, with free and independent States out of the Union. With these States, we have a common interest. Thus surrounded, shall Georgia remain under abolition rule, and refuse to unite with her sister States around her? I trust not. If so, we forfeit all claim to our proud title of Empire State of the South. Why remain? Will the Northern States repeal their personal liberty bills and do us justice? No. The Legislature of one of the nullifiing [*sic*] States (Vermont) has just adjourned. A bill has been introduced for the repeal of those unconstitutional and offensive laws. The question has been discussed, and it is reported that the House in which the bill was introduced, has refused to pass the repealing law, by a vote of over two-thirds. This action has been had with full knowledge of the state of things now existing in the South, and shows a deliberate determination not to do us justice. Is further notice to Vermont necessary? I am aware that the fears of some have been appealed to, and they have been told that if we secede, the United States Government will attempt to coerce us back into the Union, and we shall have war."
None of this makes any logical sense to secede. This speach was meant to arrouse emotions to the secession cause, it is not a clear understanding of true reasons. Even with such rhetoric, Union feelings were still very strong up until Fort Sumter. The Supreme Court ruled that the northern personal liberty laws were unconstitutional and the federal laws were quickly ignored by disobedience by those state governments. Secession would not enforce the supreme court laws nor protect the institution of slavery. Those who advocated secession knew this very well and secession would result in the end of slavery not the reverse. They were not stupid. You need to look deeper than a superficial speech to find the real goals and leaders of the movement.
