I would like you to write about what would happen if the south won the US Civil War, and then went communist.
If the CSA doesn't immediately collapse within a decade, there's a decent chance of this. The majority of white Confederates gained nothing from secession, something which only benefited the planting class. Poor white southerners--small farmers and sharecroppers, miners, factory workers, and longshoremen--would very much be second-class citizens in the CSA, and if they are willing to ally themselves with a slave revolt, you could at least get a revolution, albeit one which would probably end up more radically liberal or populist than Marxist and which would end in American reunification.
