This study analyzes letters to the editor in two Oklahoma newspapers during the debate over a constitutional amendment banning judicial use of the Islamic moral code called "Shariah Law." Using Moral Foundations Theory (MFT) to operationalize the moral evaluations in media framing, three morality-based frames were identified: a Patriot frame emphasizing Shariah’s harms, a Heritage frame advocating loyalty to the American Way, and a Golden Rule frame promoting equal treatment of Muslims. Each frame was related to moral foundations that align with particular political ideologies, and amendment supporters were more likely to frame their arguments in moral terms.
