The "Lost Cause" mythology is present in the lyrics of "I'm a Good Ol' Rebel," which was a popular folk song among white Southerners after the Reconstruction in the following way.
The "Lost Cause" mythology tried to justify slavery and the benign relationships between the slave and his master, while the lyrics of "I'm a Good Ol' Rebel" tried to reinforce that the Constitution of the United States that disallowed slavery was flawed.
The singer hates the Declaration of Independence because it also intrinsically declared all men free and equal before the law. The Declaration of Independence became the fulcrum for the Emancipation and the Civil Rights Movements.
Thus, since the singer was a Southern soldier, who cherished and profited from slavery, he did not have any qualms about its continuation and would do everything to abhor the document that laid the foundation for ending slavery and even the efforts to rehabilitate old slave laborers.
