If Texas were to attempt secession (and I don’t think they will) they woouldn’t be the only state. OK would surely follow and then probably a couple western states.
Also, IIRC Texas supplies more soldiers than any other state in the union. The front line military is pretty much made up of rural southern white boys many of whom would refuse. It would truly be a mess.
“It would truly be a mess.”
Anyone else remember those scenes in “Gone with the Wind” where Rhett tells of the southern gentry that they’re fools?
Quick, someone with this mindset go visit Richmond. Take side trips to Fredericksburg, Petersburg, Spottsylvania, Wilderness, Malvern Hill, Manassas, Gettysburg, Sharpsburg...
Then go to the Museum of the Confederacy (which is one of the best anywhere) and see what the CSA people were trying to accomplish. Compare it to what you’re saying today (and a few in Virginia still say). You will find kindred spirits.
And, you too will end up with tons of monuments and 100 years of poverty should you try.
