Hell, at this point I'd settle for their praising Longstreet.
The bar for being lionized is still gonna be pretty low in America, but I think it needs to be above the line where your one and only notable contribution to history is fighting a war to explicitly to preserve slavery, and one where most of the officers had taken an oath that would give them an easy out. Hell, the North was barely even trying to end slavery, just to kind of begin the process of winding it down through the natural progression the contemporary "democratic" process. That milquetoast bullshit was what southern elites thought was worth full-scale war. SMH.
