'I think', if Nick Kyrgios had acted the same way and got the same punishment, it wouldn't be because he's a man, it would be because hes an ** and that would be the last of it. Serena Williams acted like an ** and made a fool of herself (in front of her home crowd no less) as a self-proclaimed role model for young women everywhere, but chose to play her bonus bamboozle card and call the gender politics brigade in to cover her arsery.
Furthermore, a player of her experience surely must know that this umpire is widely-accepted as a stickler for the rulebook and won't bend to player power. Even at Sunday league football level, if a referee is known for being a bit card-happy or Collina-esque then you know not to push it.
It's all academic now anyway but I'd be very interested to know if you swapped the umpire's gender here, would there still be an argument?
