Now you're not paying attention, are you?
I mentioned East Tennessee because you say your ancestors came from East Tennessee and you used it to illustrate how "happy whities" who held no slaves could still lovingly support the CSA.
Bullshite.
In fact, non-slaveholding East Tennessee was a hotbed of Unionist insurrection and was treated as such by the CSA, most notably in the Bridge Burning Hangings (Dec. 1861), the exiling of East Tennessee Unionists and the Shelton Laurel Massacre (Jan. 1863).
Perhaps more important, East Tennessee was only one such region, others including:
Nonsense.
There are no Northern analogies to Confederate massacres or drumhead trials of civilians & surrendering soldiers at:
Great Hangings at Gainesville, Texas, October 1862:

Neely estimated 14,000 Union arrests and identified 4,000 arrested in the Confederacy, which is per capita the same number.
But the correct answer is: zero were arrested unlawfully in the Union, while relatively equal numbers of Southern Unionists were arrested in the Confederacy, many murdered absolutely unlawfully by Confederates.
See some examples listed above.
Bullshite indeed. It is you who is not paying attention. I said my ancestors lived in Tennessee at that time. I did not say East Tennessee. Take a look at a map of Tennessee and see if you can figure out where Giles County and Marshall County are.
Perhaps more important, East Tennessee was only one such region, others including: Western Virginia Western North Carolina Northern Georgia Northern Alabama Arkansas Ozarks Northern Texas & Texas Hill Country
There were some areas. Then again there were far more areas that did not have many slaves at all but which supported the Confederacy. Like most of Tennessee for example.
Nonsense. There are no Northern analogies to Confederate massacres or drumhead trials of civilians & surrendering soldiers at: Great Hangings at Gainesville, Texas, October 1862:
Nonsense indeed. There were not tens of thousands of civilians thrown into prison without charge or trial or at best trial before military tribunals only in the Confederacy unlike in the Union. Over 100 opposition newspapers were not shut down by order of Jefferson Davis. Confiscation acts were not passed in the border states and citizens were not disarmed in the border states unlike in the union.
Massacres of black Union troops at Fort Pillow, Tennessee.
There was no such "massacre". There was a running battle there with some soldiers surrendering and some still shooting. As is always the case in such situations, if some are still shooting then the other side assumes they are all threats and shoots them all. The same thing happened the other way at Drewry's Bluff and countless other places. Congress specifically questioned Nathan Bedford Forest about this and he was able to produce the receipts for the captured union soldiers he turned over to the Confederate Medical Corps. Even the Northern dominated Congress declined to charge him with anything after looking at the evidence. This was just so much propaganda put out by the Republican newspaper in Cincinnati right before the election.
Neely estimated 14,000 Union arrests and identified 4,000 arrested in the Confederacy, which is per capita the same number.
Historians have disagreed about the numbers but 14,000 is considered a low estimate for those arrested in the union. There's universal agreement among historians that Jefferson Davis suspended Habeas Corpus less often and far fewer were arrested in the Confederacy.
But the correct answer is: zero were arrested unlawfully in the Union, while relatively equal numbers of Southern Unionists were arrested in the Confederacy, many murdered absolutely unlawfully by Confederates.
The correct answer is that is pure Bullshite. Tens of thousands were arrested unlawfully in the Union. Some were tortured and some died. There were far fewer abuses of civil liberties in the Confederacy.
