I recommend Dixie. Plus "Southern America" and the fact it is a Dominion is way too confusing.With British Patagonia and Australia would the DSA really be referred to as "the South"? Also what are people from the USA called? USAians or Freedonians sounds stupid, the existence and prominence of the DSA vetoes "Americans". IMHO I think Yankee will win out despite the complaints of Virginians and those from the mid-Atlantic states.
