Introduction <p>As we mark the 10 year anniversary for federal marriage equality, attitudes toward same-sex marriage are generally supportive though there seems to be an increasing partisan divide. Opposition to same-sex marriage has often focused on the potential impact of queer couples marrying on the family, religion, and society, a concern that remains untested and without evidence. This study offers the first national look at the perceived impact of same-sex marriage.</p> Methods <p>Data come from the American Marriage Survey (AMS), a national probability-based sample of 2,789 Americans conducted in summer 2021. We examine public opinion regarding whether same-sex marriage has had a positive impact, negative impact, or no impact on the family, religious freedom, the LGBT community, and society. Multinomial logistic regression models examine predictors of these attitudes.</p> Results <p>Results show that most Americans say same-sex marriage has no impact on society, the family, or religious freedom and a positive impact on the LGBT community. Women, sexual minorities, and those who know a same-sex couple are more likely to perceive a positive impact while Republicans, Independents, and those who attend religious services more frequently are more likely to perceive a negative impact of same-sex marriage. However, Republicans and Independents are more likely to view same-sex marriage positively if they know a same-sex couple, while Democrats show no effect, likely because they already hold supportive or neutral views.</p> Conclusions and Policy Implications <p>Overall, the anticipated fears of same-sex marriage have not come to fruition as most Americans view same-sex marriage as largely unproblematic in everyday life. These findings have political implications given the recent challenges to marriage equality.</p>
