Appalachia being more isolated might account for more blacks surviving there as as it would for Chihuahua and Sonora as would their proximity to Mexico.
However Cuba would likely be the only Confederate state where a sizable number of whites would help and actually fight for blacks.
There would be exceptions elsewhere in the Confederacy but those exceptions would be very light on the ground.
Also a large number of those would do it out of a sense of family ownership of the blacks they sheltered rather than any sense of common humanity.
Confederate states where blacks were light on the ground did not necessarily have a white population who had a more positive attitude towards blacks in any way.
I know It could sound Pessimistic and Nihilistic, but I think Hispanic population of Sonora, Chihuahua and Cuba will probably We want to Participate with a Genocide of Southern Black.
Why?
well because they think they are superior to them, they are trash and helping the Freedom Party to get rid of the “black filth to help Our Dixieland”
They still be treated better than the Black and want to show they are Allegiance to the Confederacy and are still want to “Honorary Whites”
But yeah I see your point that White people from Cuba will want to Help out and
Fighting those Gray Guards to Saved Black Neighbor or “Black Property”
They don’t want the Freedom Government to take ”their property” away to some Isolation Campsite to do you what with them.
But hey it’s better to deal with Racist Families that you knew of Your Whole life and the End of the day will helped provide Housing and Food to you than
Taken into Camps with No care of your well being to Trust Strangers who you never see and heard before in Your Life that want to Murder in Most insouciant Death possible
On a related note it has always struck me as especially unjust that Texas is the one Confederate state allowed independence. The 2 largest Confederate murder factories were located in Texas and most if not all of the white population in Texas would have known that.Based on that alone Texas didnt deserve complete independence from the USA anymore than any Confederate state did except maybe Cuba. Make them puppet states but not independent or part of the USA again. They deserve no better.
I don’t know why America will allowed Texas to Secede and be Independent country after US being staunchly Anti-Secessionist with the Mormon and all over the South
.
They are as Guilty as the Rest of South maybe even worse because they are Allowed Two Biggest Death Factories in Whole American continent on their State border
And that secession things is probably a desperate move to not be Annexed to Union.
Play besides even the Black Holocaust, why Texas have a slap on the wrist to Secede While they are guilty to as the rest of the south, they attacked the union four time in a row and There still going to have the same government of the south before Jake Featherstone take in office.
So Realistic I expected that a Texas republic could probably be short live or not even begin to exist as a Union will not allow Another Succeeding State to Seceded
(Aka Marching through Georgia: Texas Addition)
