Hardly. “Bubbas” are a modern creation of a South that has been thorougly Yankee-fied in the last hundred years. At least we are still red and not blue. And “Southron” is spelled “Southern,” by the way. Besides, there’s also the little fact that 97% of the Southern soldiers who fought in the war were men who had no connection whatsoever to slave-holding.
97% of the southern men who fought for the pretended confederacy were connected to slavery: They were conscripted as members of the militia to patrol for runaway slaves before the war, they were oppressed by the slave owners by having to compete with slave labor, and they were conscripted by the slave power to fight for the slave owners.
