JK Rowling scalds political cartoonist for his grotesquely racist attack on Serena Williams

Author J.K. Rowling joined other social media users in condemning an Australian political cartoonist for his racist caricature of Serena Williams.

Mark Knight, cartoonist for Melbourne's Herald Sun newspaper, tweeted out his response to Williams' challenge of a referee at this weekend's U.S. Open final, which she lost to Naomi Osaka after she was penalized multiple times and lashed out in frustration.

The cartoonist depicted Williams with grotesquely racist features and showed her stomping on her tennis racquet and spitting out a pacifier, while the referee and opponent are depicted as calm, slender white people.

Rowling called out Knight for his racist artwork, and for inaccurately portraying the woman who won the final match and the U.S. Open title.

"Well done on reducing one of the greatest sportswomen alive to racist and sexist tropes and turning a second great sportswoman into a faceless prop," Rowling tweeted.
