The irony here is that West Virginia is still officially listed as a southern state.
I don't think that the South and the Confederacy are synonymous. There were a lot of Southerners from all over the region in the 1860s who did not drink the Confederate Kool-Aid. It's sad that the latter-day myth of the "lost cause" promotes a non-existant wartime "Solid South" that now tries to make Southerners feel like regional traitors if they don't feel sympathy for the slave owners' rebellion.
