That is where you are totally wrong, Yank. My ancestor who fought for the Confederacy FREED his slaves, because he felt slavery was wrong. My Texas ancestor was a cattleman & rancher, who didn't own any. I have always believed that it was wrong, but refuse to buy into the Yankee Propoganda line, that most slaves were mis-treated, because they WEREN'T. Think what you want, misguided as you are......
But the essential element is not who treated their slaves well, but that slavery itself was an abomination and any government that continued to support that was itself in danger of being rent asunder. Every civilized country got rid of slavery . . . but the Confederacy went out of its way to SECURE property in slavery.
Moreover, have you ever heard of slave bells? These were absolutely common on any plantation, affixed to slaves so they could not run away. Check the court records of AL, LA, MS, or GA for the recurring issues of violence against slaves, some of which was against the law, but which was almost NEVER prosecuted and/or for which people were never convicted. That one Texas cattleman freed his slaves is nice, but is akin to a Japanese soldier on the "Death March of Bataan" saying, "I gave a GI a drink!"
