In the 2018 US Open Final, Serena Williams got into a fight with the chair umpire, Carlos Ramos. When the fight got riled up, Williams called Ramos a “thief” and was given a penalty for verbal abuse.
Male players admitted to have said much worse and not been penalised.
Because when a woman gets emotional or riled up during an argument, it’s a “meltdown” and she’s “hysterical”. Both terms have been used by the media to describe Williams multiple times.
