That's not the case here though. She (Campbell) placed 7th on her swimming discipline which prompted her to realize that she's not able to qualify for the upcoming Olympic games. Her inability to compete in the upcoming summer games have nothing to do with America banning her; it was her own physical limitations that prevented her from fulfilling her goals.
Yes that's true. Also to be honest it abit rich of American swimmers accusing others of being cocky or disrespectful. They are the worst when it comes to this. They have history of putting down other competitiors and acting obnoxious. Heck, Phelps teammate Locte, is pretty much a dumb racist fratboy. Albeit one of the best swimmers ever. Phelps gets to talk shit cuz he is or was the golden boy of swimming. He himself was suspended before for DUI. Not the best role model.
Anyway, not saying the aussie swimmers are saints, some of them are certainly very cocky. Some are also biased against chinese swimmers like the Americans. But they are very much into the US Aus rivalry in swimming, and Americans definitely should be the last ones in the world to act indignant about trash talking.
