Nikki Haley was asked by a voter what was the cause of the Civil War. It did not go well.

52. While at the Alamo on March 6, 2018....

During the Anniversary of the final siege at the Alamo, a dressed Male re-enactor said the Civil War was the "war of Northern aggression". I had a discussion with him about that comment and mentioned that the South fought to preserve the inhumane institution of owning other human beings from Africa, also known as slavery. I mentioned also that those
states that succeeded from the Union were TRAITORS. He was not very happy with me about that and noticed my non-Southern accent.

He then asked me if I was an authority on the subject. I replied that I Minored in American History in College and that I remained a student of History ever since. When I mentioned Gettysburg, Richmond, Charlottesville, Petersburg, and other Civil War battlefields I had been to, and the failure of Pickett's charge, he shut up. People around me gave me weird looks that I knew more about our History than they did.

Needless to say, I am not a fan of revisionist history.
