And even if it was consensual, and even if she walked into the room and said "How about it, big guy?": does anyone here think that it's remotely normal for the head of a major international organisation and potential candidate for President of a state with strategic nuclear weapons, to have a casual sexual encounter with a hotel employee ? What does that - on its own, without any need to dig into his past - tell us about him ?
"What would it tell us about him?," you ask. Well, it would tell us the same thing about him as it would about her.
There is an episode of Seinfeld where George Costanza has sex at his office with the cleaning woman. When George doesn't want to be boyfriend-girlfriend with the cleaning woman, she goes to his boss and has George fired. Although the show doesn't go into any detail, the implication is that the cleaning woman is not fired. A man and woman have consensual sex in the office. The man is fired. The woman is not. Man bad. Woman good. An no, there was no power relationship here.
We see this throughout society ... Clinton, Spitzer, Schwarzenegger, Weiner. When a man engages in some sort of consensual but socially forbidden sexual behavior, the man is vilified, the woman is not. (And Gloria Allred always seems to turn up in these cases - she doesn't seem to recognize her own sexism.)
I can't speak about what happened with Strauss-Kahn and the hotel maid (in fact, the initial media reports made me think he was guilty). But if the hypothetical scenario you poise is true, why on earth would I vilify him? I find it ironic that it is politically incorrect to object to homosexuality but it is perfectly acceptable to condemn men for casual (consensual) sexual activities with women. More so, in the scenario you describe, it would mean that the hotel maid was using false accusations in an attempt to convict him of a felony. So if the incident really happened in this way, I wouldn't be condemning him or his behavior. Instead, I would be asking that she be sent to prison for 10 years for the false accusations meant to ruin another person's life.
