The original is a very human reaction to events. It's personal. It's not making any sort of political statement, even though it's from the viewpoint of... aw hell, from the Wikipedia article:
"The song is a first-person narrative relating the economic and social distress experienced by the protagonist, a poor white Southerner, during the last year of the American Civil War, when George Stoneman was raiding southwest Virginia."It tells a story, it doesn't make a political statement.
I don't want to continue with an off-topic, unhelpful opinion. The on-topic response, which also isn't helpful, is that the guy mumbles enough that I wonder if he WANTED anyone to understand him. I can't make out what he's singing. Add that to the fact I don't like what he did, so I don't care to try. I hope someone else can help.
