It is always the right time to protest sexism!

sportsmanship. Why are people trying to blame it on sex? It has nothing to do with her being a woman, it has everything to do with her behaviour which was unbecoming of a champion.

Was she trying to break he opponents rhythm? I have seen her do these things in the past, has everyone forgotten when she threatened a lineswoman at another US Open to shove a tennis ball up he throat? The Lindsay Davenport "injury" at the Australian Open in 2005?

Yes, Serena has done a lot of that stuff in her career, and her behaviour was awful during this year's final. Had Osaka done what Serena did, everyone would be criticizing her...double-standards are never good.

He pretty much makes it black and white as to how people treat women who get angry as opposed to men. Also those familiar with the sport suggest women are more likely to get penalized like this if they get angry and men get a slap on the wrist. Studies show this in all aspects of life. It's just a fact of life: https://asunow.asu.edu/20151027-study-shows-angry-men-gain-influence-and-angry-women-lose-influence

Here John Mcenroe's brother says he thinks gender bias played a roll. 3:35 mark:

would rattle any player, especially the best player in Tennis right now. And in the second set Serena was barely keeping up with the Haitian-Japanese player, it was 3-3 before Serena smashed her racket in frustration.

In that situation, I would have done exactly same tactics as Serena did, do break rhythm of her opponent.

It is also true that male players do not get penalized as often.

But they probably cheat and break racquets more as well. Sera's coach is right. Coaching in pro tennis is widespread. They need to either crack down on it more or change the rule.

or on any sport for that matter.

"In that situation, I would have done exactly same tactics as Serena did, do break rhythm of her opponent."

I played tennis at a high level, not the pro level but the college level, and yes I played against people who wanted to play games to try to break my rhythm, I immediately stopped them on their tracks, but I never took that kind of tactic like Serena did. I tried to break their rhythm by changing my strategy on where I would place my shots, hit more to their backhand, or play it short, etc., trying to use my brain to outsmart them.

To this day, one of my best matches was against a guy who killed me on the first set, 6-1, but on the 2nd I found his weakness and I exploited that. I ended up winning the match. What made it more significant for me was the fact that at the end of the match, as we shook hands, he congratulated me, and this is what he said, "that was one of the most fun I have ever had, even though I lost, but you beat me by playing intelligent, and I tried hard to do the same, but at the end I didn't do it, congratulations."

And with Serena's experience, she should have tried to outsmart her opponent instead to trying to rely on childish strategies. That is like the child at the store throwing a tantrum because his/her parents won't buy them a toy.

To condone bad behaviour, to believe that unsportsmanlike behaviour is OK is exactly what trump and the republicans think about governing, they strongly believe that cheating is ok as long as they reach their goal (means to an end). I don't agree with that, I would never break a racquet to throw off my opponent, if I did I would never look at the trophy with the same satisfaction as I would by outsmarting my opponent, deep inside I would know I cheated.

Golf! And it is a sport of self-controlled honesty. But people cheat on their score, improve lie of the ball which is illegal most of the time. And they mark the ball on the green to shorten the distance slightly. Female golfer Lexi Thompson was penalized 2 strokes for marking the ball incorrectly on green, a few months ago. We had a guy in our company golf league, who was terrible golfer, and when asked what was his score on the last hole, it was never higher than double bogey. I never understood why he cheated because the only prize was a trophy for a few top scoring golfers.

Point is cheating in sport is everywhere. But using psychology on the opponents is not cheating, in my opinion.
