Why Do We Root for Tiger Woods?

First off, I confess that I always root for Tiger Woods. And honestly, I have no good explanation why. Throughout my life as a sports fan I only root for two teams...my home team and the underdog. That's it. And I know I'm not alone in that respect.
So why then do I root for Tiger Woods? He's always the heavy favorite. He has ruined life-changing moments for dozens of underdog golfers. He's arrogant. He's not nearly as nice as we thought he was. He's one of the worst tippers in the game. He's not the family man we thought he was. He throws his clubs. He cusses on the golf course. His spits disgustingly on national TV (a spit you know is just another way of saying, "F*ck me!") He has little apparent respect for his opponents. He often chokes in the big team events when I should be rooting for him. Am I leaving anything out?
The normal thing for me to do would be to root against Tiger Woods. That's what a normal sports fan would do--root for all those underdogs who have failed against him. But I don't and I can't explain it.
When I argue with those few friends of mine who despise Tiger Woods, I know they are right. But that doesn't change anything for me. I still root for him. If he's not playing, I don't even watch. If he's playing but not in the hunt, I don't watch either because we all know he only wins as a front-runner--another reason not to root for him.
To make matters worse, I know there are millions of other fans just like me who are rooting for him too, which is another item for the "Do Not Root" list. I don't root for the Yankees, I don't root for Notre Dame, I don't root for USC, I don't root for the Lakers or the Celtics. In fact, I often despise anyone who does root for those teams unless they are from those towns. There's nothing I respect less than a fair-weather fan. One of my favorite things to do is to say to someone who is rooting for the Yankees, for example, "So, what part of New York are you from?" And when they say they are not from New York then I really let them have it.
I'm digging my own grave here, right? So why on earth do I root for Tiger Woods? I simply have no good answer for that one. Maybe it's time to correct the error of my ways.
