Thing is, Ramos started the whole thing by calling her for coaching, when she had her back to Moratoglou, but I know you mean if he'd not docked her later for yelling at him and smashing her racquet.
Moratoglou started the whole thing by coaching. Ramos did what he is expected and payed to do. I really, really, really don't understand how people actually want that he
did not enforce the rules. I mean, just put yourself in his position: he just spotted the guy coaching her. It is clear for him. You really think that he should just turn a blind eye? He is supposed to watch for coaching, on both players. He spotted and called it. How in the world this is wrong? And, mind it, being a first offense it was just a warning. He should not even
warn the player? How in the world is this supposed to work?
There would be a problem if he applied different criteria for each player. As far as I know there is no evidence of that.
Changing sub-topic, thanks for the reference of the article:
A few things:
1) If it is true (more on this bellow) that men and women are treated differently, in tennis this means that rules are better enforced for women than for men. Remember that the rules punish the offender and protect the other player(s), the spectators and the game as a whole.
2) One thing the link (which is not the article) fails to mention is that men (on average) do behave more aggressively than women (this is not bias, it is actually observed behavior, which was an (assumed) basis for Freud's analysis (for example) but later on largely supported by research). So the context for men and women
is different.
3) From the article's abstract:
"The results
suggest that referees made harsher decisions in female than in male matches.
Although more research is needed, this study supported the hypothesis that referees
may use the gender of players as a powerful judgmental heuristic for deciding how to respond to aggression." (my emphasis)
First, having 2) in mind, this would not be that surprising. Second, the abstract leaves clear that the research results are not decisive. But pay attention to the last phrase: this shows that an umpire must decide (and this is quite fundamental) if the subject (player) is being or not aggressive, assessing the level of said aggression and then respond to it. So, again, taking into account if it is a man or woman it is part of this judgment -- umpires do not
expect women to be as aggressive as men. Well, as I put above, on average men are more aggressive than women. In other words, man will curse more. This is a
reasonable bias. It does not give men any "unfair advantage". To assume that this is equal prejudice, and, worst, to assume that this prejudice is behind the decisions on Serena's case is, well, simply wrong. And, as I called attention for at the time, it paints one guy simply doing his job as a racist and misogynist. The unfairness in this really baffles me.
