Attempted rape is not "seduction"
One, echoing the aristocratic mentality of a bygone (well, bygone to most of us) era, vents shock that a man of the power élite could be manhandled and humiliated for such a trivial peccadillo. This attitude is widespread among the chattering classes in Strauss- Kahn's native France (though French voters may view things differently; his Presidential hopes are now toast). Strauss-Kahn was well-known as a serial seducer of women, which in France is normal male behavior; if he hadn't set foot in the priggish USA, he wouldn't be in this mess.
The other meme uses the Strauss-Kahn story as just one more example of the problem of "tomcatting" males, conflating it with Schwarzenegger, Berlusconi, Gingrich, Bill Clinton, etc. All "illicit" sex is basically the same, and why can't these guys just keep it in their pants?
Both attitudes are sides of the same coin; both depend on blurring the crucial distinction.
Strauss-Kahn may well be a seducer, but what he is accused of doing in New York was not seduction but an attempt to force sex on a non-consenting person. If he had merely seduced her into consensual sex, most likely no one would ever have heard about it, and the police would have taken no interest even if they had.
His act crossed a sharp dividing line which "tomcatting", as such, does not, no matter how offensive some people find the latter. The world is full of people who object to various kinds of sex, but in many cases they're really objecting to human nature.
Some people have a taste for partners of their own gender. Many men have a taste for partners younger than themselves, and many women have a taste for men with status and power. Adultery may raise breach-of-contract issues, but so many people find strict monogamy so difficult to stick to that it's hard to uphold it as a realistic universal standard. No one knowledgeable about the sexual behavior of our fellow great apes could doubt that all these tendencies are hard-wired into humans.
I've often harped upon the sexual transgressions of conservative politicians and preachers, but the issue there is their hypocrisy in proclaiming the supremacy of standards they themselves do not follow, rather than the transgressions themselves.
Illicit consensual sex (even Gingrich's revolting cruelty) shouldn't be, and in most cases no longer is, a crime. The use of force to get sex must be. If Schwarzenegger did what it appears he did, then he deserves to be dumped by his wife and (if they feel so inclined) by the voters of California, but no more. If Strauss-Kahn did what he is accused of doing, he belongs in prison.
