Those on the left, in the dozen or so instances which I came across, almost universally qualify their discussions of Mr Wiener’s recent passing out (exchanges of) PG-13 (and worse) photo’s of himself with a number of women. The qualification includes some sort of admission that “well, there’s nothing wrong with *that*). This is sort of a generic meme on the left. Whatever might be your fetish, it’s OK so long as its between consenting adults. How you know that the person with which you correspond over the Internet is anyone’s guess. However the premise itself is suspect.
Mr Wiener has been engaging in a electronic version of the guy in rubber galoshes in a raincoat whose fetish consists of exposing himself to women. If the public exposer used a defense that “he got consent” and “they women to whom he exposed himself told him they were of age” that doesn’t change the fact that this is nebishy behavior. And that is going to be the electoral poison that kills his career. Not there is a sexually tainted skeleton in his closet, but that his particular skeleton paints his character as one worthy of contempt.
Mr Clinton was a serial sexual offender, but his offense didn’t (apparently) paint him in the same corner as the raincoat wearing creep but as a powerful man with an out of control libido, both qualities that have tacit approval in some quarters. Commenter Boonton suggests that sexual hijinks in the future coming to light will have less and less impact. That may be, but those foibles and fetishes which come to light which paint you as immature at best or as weak or weird will not become more and more accepted.
It is not American puritan influence public sexual ethics that most obviously end Mr Wiener’s public career. It is the particulars and what picture they they, rightfully or not, paint of his character.
