ironfoot, in the words of President Jefferson Davis, who opposed secession, I remark that many Southerners knew full well the implications secession would bring, and also knew of the many benefits of being a part of the US Union, and how hard it would be to give up those benefits.
http://teachingamericanhistory.org/library/index.asp?document=491I wish everyone would read the whole speech, but the section that most relates to this topic states:
A State, finding herself in the condition in which Mississippi has judged she is—in which her safety requires that she should provide for the maintenance of her rights out of the Union—surrenders all the benefits (and they are known to be many), deprives herself of the advantages (and they are known to be great), severs all the ties of affection (and they are close and enduring), which have bound her to the Union; and thus divesting herself of every benefit—taking upon herself every burden—she claims to be exempt from any power to execute the laws of the United States within her limits. So they knew what they were doing, what they were giving up.
