Willingham isn't a tennis star, but she is a black woman.
"I drew this cartoon Sunday night after seeing the US Open final, and seeing the world's best tennis player have a tantrum and thought that was interesting", Knight said in the Herald Sun.
"(He could have said), "Hey, we're getting out of hand here, let's tone it down".
The National Association of Black Journalists in the United States denounced the cartoon as "repugnant on many levels". "Any time we step out of that lane, then we become a problem". Critics said it portrayed racist stereotypes.
"He needed to tell Serena - he can't apologise he did the right thing there, he can't apologise, he's got to be the boss - but all he had to say to Serena is "I am not attacking your character". It shows that all three code violations issued to Williams were correct. An indignant Williams emphatically defended herself, denying she had cheated.
Andy Murray kicked a ball at an umpire's head during a 2016 match, but did not get a code or point penalty.
Williams directed remarkable rants towards Ramos, who handed down a series of code violations on Arthur Ashe Stadium - the former world number one claiming women are treated differently to men following her 6-2 6-4 defeat.
"She's going to be a superstar and she already is, but now it's just the beginning", King said.
Widmaier said the feeling at USTA is that there needs to be a push to ensure consistency in the application of the rules, including coaching violations and shirt changes by women players. Another site notes that "There is also concern that the controversy could have a trickle down effect to the grassroots of tennis where there are struggles to attract people to umpiring".
"I was deeply offended".
Still, even Navratilova acknowledges that Williams has the "scar tissue" of being treated unfairly at tennis events over the years, including at the U.S. Open. It comes out of her $1.85 million prize money, according to The Associated Press.
Many have taken to social media to call out Knight's racist and sexist cartoon. "It's like our opinions don't matter".
"It's exhausting", said Denise Daniels, 44, of the Bronx, who works in professional development for educators.
Sadly Williams has faced this treatment for her entire career. I'm really sad to lose the final in this tournament because I had too much passion playing the final, trying towin the title again.
