节录一段个人觉得写得很好的：
事发之后，我们无法得知小威如果是个男选手的话，她的言行是否就得以不受惩罚。但我
认为，如果我们把焦点放在这儿的话，那是搞错重点了。如果男选手做出相同行为却受到
主审不同的对待，那么这个制度需要被彻底检讨并改正。但我们不能够以“怎么样做可以
逃过惩罚”作为审视自己的标准。事实上，这正是所有选手都应该在场上避免的行为。我
自己在比赛时有许多次都想要把拍子砸成千百断，然后我想到还有孩子们在观看比赛，于
是我不情不愿地继续把拍子好好握在手中。
It’s difficult to know, and debatable, whether Ms. Williams could have gotten
away with calling the umpire a thief if she were a male player. But to focus
on that, I think, is missing the point. If, in fact, the guys are treated with
a different measuring stick for the same transgressions, this needs to be
thoroughly examined and must be fixed. But we cannot measure ourselves by what
we think we should also be able to get away with. In fact, this is the sort of
behavior that no one should be engaging in on the court. There have been many
times when I was playing that I wanted to break my racket into a thousand
pieces. Then I thought about the kids watching. And I grudgingly held on to
that racket.
