There's no such thing as "playing oppressed Olympics." Sounds racist. Can't people have a normal discussion about race? I don't see any harmful bickering or racism.
Oppression Olympics doesn't necessarily have to do w race. It's basically defined as someone saying something, for example "I have a broken leg" and then someone else responding like "oh yeah? Well, I have cancer!" And then they bicker back and forth over who has the worst life.
