serena williams faced sexism her entire career. >> that's not what this was. she's totally out of line. >> it absolutely makes her more likely to see it. to see it in a vacuum without talking about her being penalized for other things, you know, she was one of the major factors in introducing video replay because of all the calls going against her. she can't wear the cat suit at the french open that she was wearing for health reasons. she has put up with a double standard her entire career. i think to see this one call in a vacuum without considering that larger context is a mistake. that's what she is feeling. >> don't you have to look at each call in a vacuum? in realtime, in a tennis match, the chair umpire's job to think of that player in the broader context of their career? are they supposed to call them as they see them at that moment?
