You’re correct, stadium environments are different. I should have been more clear in what I wrote. I was talking about the general concept / principle of being ejected for cheering against the opponent or a player. Since golf is such a mentally challenging sport and spectators are given the luxury to be close to the players I’d agree that commentary prior to the shot is unquestionably in bad taste. However, if a guy wants to cheer for a ball to go in the bunker while it’s in flight then so be it. I personally would never do that but that should be his prerogative is what I’m saying.
Let us keep in mind that the reason Justin made $1,200,000 this week is because of the fans. If they have to put up with some crap I don’t feel terribly sympathetic. Let your play do the talking for you. He stuck that ball on 18 like a savage. That is enough of a reply to the heckler.
