In 2004 the first legal same-sex marriage in America took place in city hall in Cambridge, Massachusetts. President George W. Bush condemned the development, as did Democratic politicians. At the time most Americans agreed—polls showed nearly twice as many opposed gay marriage as supported it. But public support for gay marriage swelled in the years to come. And what began as a judicial decision championed by Birkenstock-wearing liberals in one of America’s most progressive states became the law of the land ten years ago, on June 26th 2015, when the Supreme Court ruled in Obergefell v Hodges that gay couples have a constitutional right to marry.
