I will never watch another Serena Williams tennis match, commercial, etc. She is a disgrace to American tennis and American women in general. I will neither purchase products made by those companies that endorse her behavior...Bruce Dan

Venus Williams is a female tennis player (born June 17, 1980) who excelled in, if not dominated the sport for much of the 2000's, and played competitively into the following decade. She was three times ranked #1 woman player in the world (the first black female to attain that ranking) winning 21 Grand Slam events. Ironically, her sister Serena (a year younger) became even more successful, and the two were often paired in doubles, winning more than a dozen Grand Slam doubles titles (including 3 of 4 in 2009).
