If their coaches are letting the athletes see Twitter commentary, the coaches are fools.
What's the big deal about an Olympic gymnast's being black, anyway? I remember when Dominique Dawes was competing - another bright, pretty girl and great athlete.
She had not seen it. A reporter told her about it, so she googled herself afterward and was just flabbergasted at what she found. I think it is beyond disgusting. This little girl worked so hard and was the best of the best, and then she was told that was not enough.
