Yeah, how dare those Olympians use a symbol of unity against legalized oppression back in the 60s, when black people were fighting for the same rights white people had. In the '60s, a raised fist wasn't just the symbol of the Black Panthers; "Black power" was a term used to get people out on the streets and joining in sit-ins, marches, and other forms of protest. It was simple and catchy, and so it caught on. And for the record, the moment Crissi mentioned happened in the 60s. The Bronze Medalist who joined the two black Gold and Silver Medalists was a white Aussie whose experiences with Apartheid showed him that those medalists were fighting a good fight.
You may find Crissi's statement disgraceful, but I find your historical ignorance moreso.
