Not so. The South had the much better philosophical and legal position in the CW. Just not the power. 150 years of government school propaganda has erased that truth, but scholars know it.
What passed for legality, and political quorums during the Cw in the South could hardly be called exemplary.
The philosophy of the South was the philosophy of the democrat party; period.
Lee urged everyone to come together as a nation under the Constitution after the war ended. Unfortunately, to this day some still hold to the philosophy of the democrat party.
