One nuance that I think often gets lost is that outside of a very small percentage of cases, if your great great great grandfather fought for the confederate army that isnt a criticism on you or him. Theres every likelihood that he was just another illiterate idiot fed a bunch of rhetoric and told who to fight and be vilified, press ganged or killed if he didnt. Even if he volunteered, look at the lies and dripple being punched out about russia/ukraine and israel/palestine and they had a very narrow information flow. Its ok to have family on the wrong side of history, we cant know what kind of person they were or how they really felt in most cases.
