Tiger Woods is the only person guilty of anything in that situation.
Yeah that bothers me... I mean. He's married, why are the girls in this situation the only ones being called slutty?? There was a case over here of a well known model who had a short term thing with an AFL player, who just so happened to be married. Being from Sydney, she had no idea about him (AFL is a very Melbourne thing, and most people in Sydney think it's ridiculous.. anyway), so she looked him up online and found someone referred to as his, "wife". She asked him about it and he said he was divorced. It was only when she was visiting friends who told her his wife just had a baby, that she realised he was lying and she dumped him on the spot. His wife embarked on a major publicity stunt (they're still married) and frequently give interviews about the situation and to plug their new restaurant. The model is also now known around the country as a bit of a slut really, and while she's certainly not the smartest girl in the country, slutty she is not.
That said, I don't buy that these ladies with Tiger aren't guilty, I mean, it's not hard to google the guy. It's not like they don't know who he is and he wasn't honest with them about being married - on the released voicemail he clearly talks about his wife as if it's perfectly normal to mention her. It's totally disrespectful in my opinion - but completely wrong that he isn't the one copping the brunt of the blame.
