Do you defend marriage or respect it? If the question is confusing, just remember that the Defense of Marriage Act banned same-sex marriage, and the Respect for Marriage Act allows it.
Line chart titled “Should same-sex couples have the right to marry?” Subtitle “Percent supporting marriage rights,” GSS. Estimated support rises from about 12% in 1988 to about 66% by 2020, then levels off through 2024, with a shaded uncertainty band around the time-series line and survey points as dots.

In 1992, only 28% of Americans said gay couples should be allowed to adopt children. But support grew quickly: by 2008 it was above 50%, and in 2024 it was above 80%. During that period, state laws were all over the map.
Line chart titled “Should gay couples be allowed to adopt?” Subtitle “Percent favoring adoption rights,” ANES 1992–2024. Estimated support rises from roughly 28% in 1992 to about 81% by 2024, with a shaded uncertainty band around the time-series line and survey points as dots.
