If the rebels are to be considered US veterans and not foreign nationals, then they were indeed engaging in treason. 

Can't have this one both ways. Either these statues are of foreign soldiers who fought against the US, or they are of US soldiers engaged in treason. Either way, they need to be removed.

They further need to go because the intent of putting them up during Jim Crow was to intimidate black citizens. Simply disgusting white nationalism, may it hit the scrap pile of history sooner rather than later.
