Snooker legend Ronnie O'Sullivan says female referees should stick to women's sport following Serena Williams row - he cannot be serious?

Ronnie O'Sullivan says female referees and umpires should stick to women's sport following the Serena Williams row. The snooker legend said: "Female referees are very good but maybe females should referee female matches because they understand how a woman thinks. Maybe men should just referee men's matches because they know how men think. This was what I was thinking when Serena Williams was playing. Men and women are different. They think differently. And men don't really understand women. If a woman was refereeing another woman then she can go: 'Oh, I can understand maybe how she is feeling'." What do you think of that? Does he have a point?
