John Roberts has made some decision that have given conservative reason to worry about the future. But, remember, wrote a blistering dissent in the gay-marriage case Obergefell v. Hodges. There he said clearly, “[T]his Court is not a legislature,” and grouped Obergefell with two of the Court’s most disdained decisions, Lochner v. New York and Dred Scott v. Sandford, concluding by declaring that the Constitution “had nothing to do with” the majority’s ruling.
