You’re right. It shouldn’t have gotten to that point. Serena should have been more composed. If everyone does it, which they do, then she shouldn’t be berating the umpire and calling him a liar. If no men’s player, which I doubt, has ever received three warnings and a game misconduct then the umpires were way too lenient. Then again, I highly doubt the whole narrative.
And, her history has relevance. Referees are quicker to nab Doc Rivers because he complains about everything. Don’t want a quick trigger, fix your damn behavior.
