Well I guess it depends on your personal values. But How would you want to raise your own daughter? How would you want your daughter to behave?
For me, being rude to everybody is not a trivial matter. Constant complaining shows her internal personality. She has no respect or gratitude for people.
For me, Zhang Ning was an elegant and beautiful person, always gracious and respectful to people.
I beg to differ, not so much personal values as broad-mindedness. I believe we can and should cut her some slack.
The two examples you brought up are, in my view, understandable situations. In the one instance, the two ladies were at it in the final of the AE like nearly two hours, exchanging blow for blow and grappling for every single point whilst their fatigue and stress levels were unusually high. The difference is WSX wasn't 'clever enough' to dive and fall to the ground for the floor to be mopped and/or tying her shoelaces to buy time as her 'more likeable' opponent Nozomi was doing as otherwise the umpire might've been kinder to her delaying tactics. In the other instance, the poor girl hurt her back, another stressful situation, which required medical attention, and I venture to guess, maybe the medic was spraying a little too much analgesic on her back while lifting up her shirt and lowering her shorts a bit too exposed, thus her somewhat curt reaction. (Didn't LXR afterwards took over the spraying and even massaged her back and helped to carry WSX's kit bag? Is that the match we're talking about, sorry if I recalled not too accurately from memory).
Moreover, we know WSX to have quite an outspoken personality who once openly expressed her disagreement with her coach Zhang Ning but later didn't they made it up and become on good terms with each other as known and shown on TV in subsequent tournaments?
Pardon me for saying this, mate, your particular dislike of her reminds me of those LCW fans who just can't stand Lin Dan for often besting their idol and reducing him to a miserable state so much so that the sight of Lin Dan's victory celebrations, his on court supposed swagger (much less so nowadays, esp after LOG'12) and even his occasional blowing his nose to the side of the court, get on their nerves. Such a fixation on Lin Dan can only mean one thing, jealousy and sour grapes. If only Lin Dan had lost a couple of those big matches to their idol would they find him more acceptable if not more pleasing or charming. Well, to each his own then but let's not be petty about it.
You know, compared with tennis legend John McEnroe's antics and famous (should I say, notorious) confrontational behaviour, outbursts and tantrums,for which he was slapped with a fine several times for his altercations with tennis authorities, WSX's or even Carolina Marin's or Bo/Mo's or a certain MAS MD pair's or INA MD pair's indiscretions looked more amusing, perhaps a little irritating, than obnoxious, in my opinion (and my intention is not to drag these others into the discussion here). Yet until today JM still has his die-hard fanbase. (To be frank, he's a bit too much for me).
However, like everybody else, I'd like to keep our beloved badminton as a more civil, cultivated, respectable and gentlemanly sport. So far so good.
