The writer is confused or deluted if he thinks that the Seinfeld characters consititue role models that any sane person would want to emulate. Indeed, as the show went it, it became more and more obvious that the ideosyncracies and personal flaws made it impossible for any of the main characters to lead happy, fullfilling lives. This was especially hammered home in the last episode where E,G,J,& K are sent to jail, not so much for the minor offense for which they are charged, but for their behavior over the past decad--very Camus-eske! If some Liberals indeed display this behavior, I would say that Seinfeld parodied it, rather than promoted it.
The style and themes of Seinfeld are being repeated in the "Curb Your Enthusiasm" series on HBO (Larry David). I enjoy them both, but don't think anyone in their right mind would claim these are role models.
"role models that any sane person would want to emulate"
Sane? He's talking about liberals.
