Serena Williams' husband calls controversial cartoon 'blatantly racist'

The husband of tennis superstar Serena Williams has hit out at the Australian newspaper behind a controversial cartoon of his wife.

Alexis Ohanian, a co-founder of Reddit, called the cartoon by Mark Knight "blatantly racist and misogynistic".

"I am truly perplexed to learn this editor of the Australian newspaper behind the blatantly racist and misogynistic cartoon of my wife is a 'Male Champion of Change'. Is this supposed to be satire, too?" Mr Ohanian tweeted.

The cartoon, which showcases Williams jumping up and down with a baby's dummy lying on the ground by her, has been criticised by many commentators and social media users.

Dr Jason Johnson, a professor of politics and journalism at Morgan State University, said the cartoon was inherently racist, reported Yahoo!.

He said it depicted Serena as "brooding, big-lipped, almost ape-like [as] black women in America and black women's bodies have been racially portrayed in the past".

Since the cartoon's publication, the Herald Sun has backed itself, publishing follow-up cartoons hitting out at its critics, while Mr Knight said it was only meant to be about Williams' behaviour and not about race.

Williams is yet to comment on the cartoon.
