Ya, I agree with all of this.Patrick was attempting to coach Serena, probably deserved a warning. Patrick was wrong.
Serena over-reacted and breaking her racket was beneath her as was her temper tantrum after she received the penalty. Serena was wrong.
The umpire went over-the-top with the game penalty because Serena called him a thief. If you're that thin-skinned you have no right to be an umpire and much worse is said to umpires every day without any repercussions. Umpire was wrong.
Serena calling this sexism, is harmful to women. It minimizes what "sexism" actually is. There were two women on that court and for Serena to claim "sexism" is illogical and stupid. Serena was wrong.
The US Open fans that booed Osaka are idiots. Osaka played a brilliant game, she is a big part of the future of Women's tennis and she deserved cheers and a standing ovation. US Open fans were wrong.
But I will say it is a bit strange for the umpire to call a code violation for coaching when it is common for all coaches to do this (Toni Nadal doesn’t even try to hide it; Brad Gilbert brags about giving Agassi hand signals all the time).
But on the other hand, once it’s called, I don’t agree with a player abusing the umpire for it. It is his discretion. Serena needs to just accept it, move on, and play the match.
And I really don’t agree with the media backing Serena and basically encouraging players to do what she did when they disagree. That’s a terrible thing to be teaching to the young tennis players out there.
