Serena Williams complains of sexism

"I’ve seen other men call other umpires several things, and I’m here fighting for women’s rights and women’s equality and all kinds of stuff, but for me to say 'thief' and for him to take a game?It made me feel like it was a sexist remark. I mean, he’s never taken a game from a man because he said thief. For me, it blows my mind," she said.
