"Many southern whites had considered themselves more Southern than American and were prepared to fight for their state and their region to be independent of the larger nation. That regionalism became a Southern nationalism, or the "Cause" ... The "Southern Cause" transcended the ideology of states' rights, tariff policy, or internal improvements. This "Cause" supported, or descended from, cultural and financial dependence on the South's slavery-based economy. The convergence of race and slavery, politics, and economics raised almost all South-related policy questions to the status of moral questions over way of life, commingling love of things Southern and hatred of things Yankee (the North). Not only did national political parties split, but national churches and interstate families as well divided along sectional lines as the war approached"

This is only why I ask if they would ever resent being associated with a contiuned existence of the Union.

It would appear that if southern states felt so very differently than their northern neighbors to kill them, a name change in victorious success may not be so ludicrous.
