Within days of Donald Trump's second inauguration, the administration began erasing LGBTQ+ people from federal websites, while Republican governors across the country rebranded Pride Month as celebrations of the "traditional" or "nuclear" family. At the same time, public support for marriage equality has begun to slip, and conservative activists are seizing the moment to revive their campaign against Obergefell v. Hodges. Emboldened by the Supreme Court's decision to overturn Roe v. Wade, they are laying the groundwork for a new legal challenge—one designed to persuade the Court's conservative majority to reconsider the constitutional right to same-sex marriage. But this latest effort relies on a familiar myth dressed up as a new argument: that children are the "real victims" of marriage equality. The evidence tells a very different story. Decades of research—and a recent meta-analysis examining children's developmental well-being—show that children raised by same-sex parents do just as well, and in some measures even better, than those raised by heterosexual parents. The real harm comes not from loving families, but from efforts to deny them equal dignity under the law. Opponents of marriage equality are working hard to revive old attacks on marriage equality. We cannot allow this campaign of erasure to succeed.
