Greek athelete thrown out of olympics and rightly so

Greek athlete posts a joke about mosquitoes and African people and gets thrown out of Olympics.  Some people think it was a bit too harsh. I think it was just. Mainly because people are beginning to forget manners  and  say what they like. This leads to unpleasant environment in activities that involve global participation.  The Greek athlete would rather the players were all just Greek. She must play in only national sports then and not international. She has a choice.
