Change what a people are called and their standing reorganises around the name, even on the ground where they were rejected.
A verdict absorbed turns into a self-definition, and a self-definition manufactures its own evidence. People who have taken not my people as their label start living at the level of it, which hands the verdict fresh proof, and the loop tightens until the name looks like plain description.
No fact on the ground changes: same people, same place, the name traded for sons of the living God, and the standing moves with the name rather than with the history. Anyone still running on an old rejection is being loyal rather than realistic, staying consistent with a label already withdrawn, and paying for it in every decision downstream.
