Their point is the double standard. Either apply it consistently or not at all. If athletes are representing their country in all aspects when competing internationally, all athletes should be held to that standard.
If an athlete refused to shake a USian athletes hand because of the war crimes of their country, including ones ongoing at this very moment, you would be on board with it then? There would be precious few handshakes that could be given out on international sporting stages, that is for sure.
Living in Japan, this almost didn’t register to me. I have literally never met anybody that didn’t have one. When you move out, you use your family’s old one until you can buy a newer one.
Everyone should have one, absolutely.
