Yancey was a strong advocate of the right of his race to enslave those of other races; an American who long agitated for division and secession; a Democrat who was among those responsible for the split of his party along regional lines. Only if one still clings to the idea that slavery was morally good and that the rebellion was a worthwhile attempt to preserve that 'peculiar institution' might one consider him a "patriot".
But give him credit, he had such a subtle way of putting it.
"Men, who shall, after the passage of this Ordinance, dissolving the union of Alabama with the other States of this Confederacy, dare array themselves against the State, will then become the enemies of the State. There is a law of Treason, defining treason against the State; and, those who shall dare oppose the action of Alabama, when she assumes her independence of the Union, will become traitors--rebels against its authority, and will be dealt with as such." http://docsouth.unc.edu/imls/smithwr/smith.html
