Politics at the Olympics are nothing new. In 1968, two black athletes who won medals in the 200m race raised a fist to protest racial inequality, a move that got them banned from the Olympics for life. A few years later, the IOC introduced Rule 50, which reads: "It is a fundamental principle that sport is neutral and must be separate from political, religious or any other type of interference." As this year's Tokyo Games wrap up, they'll be remembered not just for the pandemic, or the heated local battles over whether they should happen at all. They are also a moment when Rule 50 got squishy. Whether it was soccer players taking a knee, German gymnasts in full body leotards, or Australian athletes holding up an indigenous flag, there's been a lot of protesting going on. And to some extent, the rules have been relaxed - though not everyone agrees they should be.
