Truth Overruled: The Future of Marriage and Religious Freedom is a 2015 book by conservative scholar Ryan T. Anderson that analyzes the impact of the U.S. Supreme Court's Obergefell v. Hodges decision (2015), which legalized same-sex marriage nationwide. Anderson critiques the ruling, arguing it undermines traditional marriage and religious freedoms, and proposes strategies for religious liberty protections, including legal and cultural approaches such as religious exemptions, conscience protections, and advocacy for restoring marriage as a union of man and woman. Drawing on legal analysis, historical context, and policy recommendations, the book has become a key text in conservative responses to LGBTQ+ rights advancements and debates over religious liberty.
