An episode in the book dealt with the early Ku Klux Klan. In the immediate aftermath of the War, Scarlett is assaulted by poor southerners living in shanties, whereupon her former black slave Big Sam saves her life. In response, Scarlett's male friends attempt to make a retaliatory nighttime raid on the encampment. Northern soldiers try to stop the attacks, and Rhett helps Ashley, who is shot, to get help through his prostitute friend Belle. Scarlett's husband Frank is killed. This raid is presented sympathetically as being necessary and justified, while the law-enforcement officers trying to catch the perpetrators are depicted as oppressive Northern occupiers.

Although the Klan is not mentioned in that scene (though Rhett tells Archie to burn the "robes"), the book notes that Scarlett finds the Klan abominable. She believed the men should all just stay at home (she wanted both to be petted for her ordeal and to give the hated Yankees no more reason to tighten martial law, which is bad for her businesses). Rhett is also mentioned to be no great lover of the Klan. At one point, he said that if it were necessary, he would join in an effort to join "society". The novel never explicitly states whether this drastic step was necessary in his view. The local chapter later breaks up under the pressure from Rhett and Ashley.

Scarlett expresses views that were common of the era. Some examples:
