…by seceding from their SCV camp.
It seems some members of Florida’s General Jubal A. Early Camp No. 556 (of ginormous Confederate flag fame) wanted to devote more of their efforts to historic preservation and education. Their compatriots preferred to focus on charitable work and PR, so twelve of the historically minded gents accordingly took their leave and formed a new camp, named for Judah P. Benjamin.
When members of a Civil War heritage group can’t persuade fellow members to engage in Civil War heritage activities, I think you’ve got a case for secession that even the most radical of nineteenth-century Republicans would support.
