Is it morally/philosophically right for an athlete to wear a protest ribbon during the Olympics?

No, I believe that it is their right to wear the protest ribbons. What is happening in China and Tibet is not okay and it's a violation of human rights. I believe that everyone attending and even those who aren't should wear those bands because it's displaying their displeasure without harming anyone or anything. They aren't even affecting the Olympic Games, just protesting the host country's actions and there is absolutely nothing wrong with that. It's especially good for an athlete to do this because they will get attention and drag these issues more into the spotlight, which must happen if anything is ever going to change.
