So the judge was racist and sexist and so ruled unfairly against her in favour of another black woman?
Or was she playing Tim in a dress?
You do realise that someone can be sexist simply because he treats all the female players different to the male players, or racist. IE he could give out penalties to Williams against Osaka but but to Federer playing Djokovic for behaviour the same way. IE different treatment of women.
The idea that treating her differently only works if her opponent isn't a female or black is... just absurd.
He wasn't sexist or racist or anything else. So many people keep trying to bring it down to she got penalised for calling him thief while other players have called him worse without penalty.
In many sports, tennis included, emotion gets the better of players and they speak out. if someone says what an idiot making that call, and literally that's it, or then as often happens sitting in their seat fairly calmly discuss it with the ump after the game that very very rarely gets penalised.
When you stand up and yell for everyone to hear easily and you do this not once but several times after several games and you basically through a tantrum for everyone to see such that your behaviour becomes distracting for the opponent and abusive in nature then you get penalised. Djokovic, Nadal, many players have been penalised when they prolong such situations and they are almost never penalised if it's one sentence and not repeated.
Serena complained about the initial warning, then she slammed her raquet, got a point penalty which is given like 95% of the time and has been for years, she complained a lot more and for a few games iirc she complained between them, then she went on a full on prolonged tired. She said he'd never work near here again, threatening his job/career, she called him a liar and thief multiple times and she repeatedly demanded an apology.
The idea it was a brief "you're a thief" then she got on with the game is absurd. When your behaviour is that bad and when you're literally distracting and upsetting your opponent then you fully deserve a penalty. There just isn't any question. It also very much seems that there is a PR push by her people to frame it as "she only called him a thief but others called him worse", I've seen that on imgur, on reddit, twitter, everywhere and it entirely reframes what she supposedly did wrong to get penalised.
