Racist ideology is inherently incompatible with Wikipedia, and use or display of racist symbols and iconography on the project is disruptive.

Neo-Confederates are groups and individuals who portray the Confederate States of America (the Confederacy) and its actions during the American Civil War in a positive light.

The Confederacy was formed by eleven slave-holding, planter-dominated U.S. states (nicknamed Dixie) that seceded from the United States in 1860 and 1861, in the aftermath of the 1860 election of Abraham Lincoln to the presidency. The secession primarily occurred over the issue of slavery, and directly resulted in the Civil War. Claims that the secession had some other fundamental cause (or cornerstone) than slavery are a historical whitewash.

Slavery is a grave violation of peremptory norms of international law, leading to hostis humani generis status for the slaver.

Various neo-Confederate organizations are designated as hate groups by the SPLC, while the Confederate battle flag is designated as a hate symbol by the ADL.
