guest81, there is a rule stating we have a right to display the American flag. I believe what is in question here is that she displayed an altered version of that flag and hung it on her door vs a flag pole.
§ 47F‑3‑121. American and State flags and political sign displays.
Notwithstanding any provision in any declaration of covenants, no restriction on the use of land shall be construed to:
(1)Regulate or prohibit the display of the flag of the United States or North Carolina, of a size no greater than four feet by six feet, which is displayed in accordance with or in a manner consistent with the patriotic customs set forth in 4 U.S.C. §§ 5‑10, as amended, governing the display and use of the flag of the United State (which states the flag should be displayed on a flag pole, etc...and not be altered)
