In Michigan, state Rep. Josh Schriver unveiled his own anti-gay marriage resolution on Feb. 25, arguing that restrictions on gay marriage are important to “preserve and grow our human race,” he said at a press conference announcing the resolution.
“Michigan Christians follow Christ's definition of marriage as a covenant between a man and a woman, an institution established to glorify God and produce children,” said Schriver.

The handful of resolutions come after Associate Justice Clarence Thomas expressed interest in revisiting the Obergefell decision in his concurring opinion on the Supreme Court's landmark 2022 decision on the Dobbs v. Jackson Women's Health Organization case that overturned the federal right to abortion.
He wrote: "In future cases, we should reconsider all of this court’s substantive due process precedents,” such as Obergefell. “Because any substantive due process decision is 'demonstrably erroneous,' we have a duty to 'correct the error' established in those precedents,” Thomas said.
Thomas had issued a dissenting opinion in 2015 against same-sex marriage equality.
More than two dozen states have some kind of restriction on same-sex marriage that could be triggered if the Supreme Court one day overturns its 2015 decision, according to legislative tracking group Movement Advancement Project. This is because marriage equality has not yet been codified and enshrined into law nationwide.
However, the Respect for Marriage Law signed by former President Joe Biden in 2022 guarantees the federal recognition of same-sex and interracial marriages in the event of an overturned Supreme Court decision.
