Nope. This isn't my reckoning -- it is your reckoning. Setting up strawmen to attack is merely a diversionary tactic.
You may argue that the 1776 Virginians were rebels who went to war against their King. You are right about that -- it made them Traitors under the law, which they understood. "The South" of 1860-61 are also putting themselves in the position of Traitors under the law, attacking their own country -- if this is what your use of "Sic Semper Tyranus" is intended to mean, you are correct in that use.
It is you setting up diversionary tactics not me. I said: They (the CS) wanted independence from the US and were willing to fight for it if necessary. You construed that to mean: “they wanted a war more than peace.” I inferred from that that you felt any people willing to defend their independence from a hostile army occupying part of their country and claiming it for their own is the guilty party. The Southern secessionist and I suspect few others elsewhere would have preferred war to peace if reassured that war was unnecessary.
