Quote from AAAintheBeltway:
Golf is different from any other sport. In other sports, if an official doesn't see it, it didn't happen.
Golfers are expected to call penalties on themselves. Bobby Jones famously emerged from thick woods where no one could see him and announced he had assessed a penalty for an infraction no one else saw.
Tiger by contrast has benefitted over the years from playing it close to the edge. He got a bunch of spectators to move a boulder that was in his way and claimed it was a "moveable obstruction." Cowed officials agreed, but the rule was later changed to explicitly outlaw it. In another tounament he hit his ball over the grandstand and clubhouse. He was ludicrously given a free drop. In another incident, his ball landed close to some woods amid a scatering of spectators. The ball was never found and officials generously ruled that a spectator "must have" taken it, although there was no evidence of that.
Tiger favoritism even seemed to extend to the US Open. Once notorious for tight fairways and high rough, the Open started using a graduated rough, where wild tee balls were not punished so severely. Who was struggling with wild tee balls? Tiger Woods.
I don't think it's fair to say people are Tiger-haters just because they have a problem with what happened. A lot of people admire Tiger as a golfer, but resent the favoritism he has clearly received. The fact that he has conducted himself poorly on and off the course doesn't help.
This incident will not go away in a week, like a bad call in an NFL game. It will follow Tiger and detract from his legacy.
