From Gallup:
After two decades of rising support for LGBTQ+ issues, U.S. attitudes have plateaued and begun to slide back modestly. Approval of same-sex marriage, moral acceptance of gay and lesbian relations, and endorsement of gender changes are all down from peaks reached in the early 2020s.
While most Americans still favor legal same-sex marriages, the 65% who do so today is down six percentage points from the peak in 2022 and 2023. Similarly, the percentage viewing gay or lesbian relations as morally acceptable, 62%, has not been lower since 2016. And the share of Americans who consider changing one’s gender morally acceptable has declined eight points over the past five years, to 38%.
