This is what I will remember about the atmosphere at the Supreme Court during the same-sex marriage cases: that it wasn’t terribly memorable. The place was relaxed. The Justices were attentive but unemotional. The audience was cheerful. It was a lot like most arguments before the Justices, except that every seat in the courtroom was taken. The reason for the mellow vibe was unspoken but clear. Everyone knows that same-sex marriage is here to stay; indeed, it’s expanding throughout the country at a pace that few could have imagined just a few years ago. The Justices were not irrelevant to the process, but they weren’t central either. They knew that—and so did everyone else.
