I dare say the Confederates put up a bigger fight than did the Colonists. Lincoln was just more willing to kill people than was George III.
The south could have tried secession - no not the phony spit in your eye unilateral secession, but true negotiated withdrawal.
Oh, they did secede. Had they left Fort Sumter alone, they would have also succeeded.
Instead they had a national tantrum and started a war they could not possibly win.
Just like the Colonists. I suppose if the Confederates had merely encountered a contingent of Union Troops and traded gunfire with them, thereby killing 73 of them, that would have been acceptable from your perspective? Obviously bombarding a bunch of rock walls while killing no one is just way over the line.
I daresay the confeds were way more ruthless than the colonists or the unionists and that they were the ones that were more willing to kill people than was George II OR Lincoln.
