Imagine this: it’s the opening ceremony of the 2014 Winter Games in Sochi, Russia. A huge television event, watched the world over. The American Olympians join the proud march of nations. They’re our emissaries, our exemplars. And as the television cameras zoom in on Team U.S.A., one of its members quietly pulls out a rainbow flag, no bigger than a handkerchief, and holds it up. Not ostentatiously high, but just high enough that it can’t be mistaken. Another American follows suit. Then another, and another. Within minutes the flags are everywhere in the American delegation, subtly recurring bursts of color and of honor, a gay-rights motif with a message: we’re here in Russia to compete, but we’re not here in Russia to assent. That’s an Olympic moment to rival any quadruple toe loop. That’s pure gold.
