It may not be your intent, but this is how racism is accepted and flourishes: by not acknowledging it or hand-waving it away. And no, "it can't be racism because then it would be blatant and obvious racism" is not an acceptable argument.

You keep referring to details not in the articles, or reasons that the judge might have had, rather than what's 100% obvious and in our faces. Watch the video. The judge had chances during and after to correct her "mistake", but no. The medals weren't too tangled to be given to the the girl before and they seemed to be untangled for the girl after. The end result was a line of young gymnasts, and the little black girl is the only one standing there not wearing a medal.

And to be clear, others share the blame for not questioning or intervening at the time. That's why this is an issue of systemic racism, rather than just one incident...
