I've heard people say that they feel betrayed by Mr. Woods because he said that family was most important to him, and his numerous extramarital affairs proved that to be a farce.
But is it? He might have slept around, but he didn't give up his marriage easily. When his wife found out about his girlfriends and hit him in the face with a golf club, he tried to blame it on a car accident. He gave her $5M to stay in the marriage. Surely he is just as concerned about his marriage as he always seemed to be.
Okay, he slept around. There seem to be two types of men: those who get caught and those who don't get caught. Don't hit the keys too fast: I'm joking. And women commit infidelities too. But come on: studies have shown that over half the population does it. Mr. Woods spent a lot of time on the road; he's movie star handsome, adorable and rich; celebrity is a powerful incitement to narcissism: it's not surprising that he got more than your average shmo.
What bugs me is the hypocricy of it all. While Bill Clinton was being impeached over a blow job it was widely known that his predecessor, George Bush Sr., was in a long-term relationship with a woman other than his wife. There wasn't any interest in ensuring that politicians keep it in their pants. All the interest was in finding out where he put the cigar.
No, there seem to be two things going on. One is voyeurism: when someone gets caught there's an opportunity to dig into their privates. Second, it's like those guys who are homophobic because they can't come to terms with their own interest in men (I don't know if these guys exist but they show up in movies quite a bit). You get to condemn the sinner, secure in the knowledge that everyone's attention is on the celebrity sinner, and nobody's looking at you.
