I've always heard it called the "Lost Cause Of The South" by racist rednecks; they seem to be aware enough (or someone was, whoever it is they're parroting) to attempt to distance it as much as possible from terminology that associates it with slavery because otherwise it looks even worse. Even though slavery is absolutely what it was all about.
But actually it was democrats who were the slavers! That's why republicans honor their democrat heritage by flying a traitor flag? Fuck I can't even keep up with their mental gymnastics.
