The most tempting offer came from “Hannity & Colmes.” As I viewed it then, Sean Hannity represented the bane of American civic life: a blow-dried blowhard paid to vilify his enemies and incite his imbecilic fans. I leapt at the chance to confront him on live TV. A producer promised me 10 minutes of airtime, during which I would be free to voice my objections to Rice, the former secretary of state. As it turned out, my interview ran just over three minutes, much of which I spent trying to fend off Hannity’s insistence that I voted for John Kerry. Not what I’d envisioned, but I managed to outlast his bullying and even launch a few zingers before my mike was cut. I was immensely pleased with myself, and I happily accepted kudos from fellow lefties. Over the past few years, I’ve come to view my appearance as somewhat less heroic. I hadn’t spoken truth to power or caused anyone to reassess Secretary Rice’s record. I merely provided a few minutes of gladiatorial stimulation for Fox News. In seeking to assert my moral superiority, I enabled Hannity. This, to be blunt, is the tragic flaw of the modern liberal. We choose to see ourselves as innocent victims of an escalating right-wing fanaticism. But too often we serve as willing accomplices to this escalation and to the resulting degradation of our civic discourse. We do this, without even meaning to, by consuming conservative folly as mass entertainment. If this sounds like a harsh assessment, trust me, I’m among the worst offenders. Yes, I’m one of those enlightened masochists who tune in to conservative talk radio when driving alone. I recognize this as pathological behavior, and I always make sure to switch the station back to NPR before returning the car to my wife. But I can’t help myself. I take a perverse and complicated pleasure in listening to all the mean, manipulative things those people say. Of course, not all right-wing pundits spew hate. But the ones who do are the ones we liberals dependably aggrandize. Consider the recent debate over whether employers must cover contraception in their health plans. The underlying question — should American women receive help in protecting themselves from unwanted pregnancies? — is part of a serious and necessary national conversation. Any hope of that conversation happening was dashed the moment Rush Limbaugh began his attacks on Sandra Fluke, the young contraceptive advocate. The left took enormous pleasure in seeing Limbaugh pilloried. To what end, though? Industry experts noted that his ratings actually went up during the flap. In effect, the firestorm helped Limbaugh do his job, at least in the short term. But the real problem isn’t Limbaugh. He’s just a businessman who is paid to reduce complex cultural issues to ad hominem assaults. The real problem is that liberals, both on an institutional and a personal level, have chosen to treat for-profit propaganda as news. In so doing, we have helped redefine liberalism as an essentially reactionary movement. Rather than initiating discussion, or advocating for more humane policy, we react to the most vile and nihilistic voices on the right. Media outlets like MSNBC and The Huffington Post often justify their coverage of these voices by claiming to serve as watchdogs. It would be more accurate to think of them as de facto loudspeakers for conservative agitprop. The demagogues of the world, after all, derive power solely from their ability to provoke reaction. Those liberals (like me) who take the bait, are to blame for their outsize influence. Even programs that seek to inject some levity into our rancorous political theater run on the same noxious fuel. What would “The Daily Show” and “The Colbert Report” be without the fulminations of Fox News and the rest of the right-wing hysterics? Taken as a whole, the arrangement is entirely cynical. This slavish coverage of conservative scoundrels does nothing to illuminate policy or challenge our assumptions. On the contrary, its central goal mirrors that of the pundits it reviles: to boost ratings by reinforcing easy prejudices. These ratings come courtesy of dolts like me: liberals who choose, every day, to click on their links and to watch their shows. So why do I do this?
