I was somewhat disappointed with the article insofar as I think the rot goes much deeper; i.e. into psychological dysfunction.
Most of us are "products" of the public school and university system. We grow up and we "get over it". I believe that those who remain within the "educational" system or who find their way into the media as a result of their talents also find themselves there as a consequence of their insecurity. Those institutions are one step removed from the real world of self-sufficiency and the individuals represented depend upon and are beholden to others for their sustenance. I think that they very deeply resent this. They are exceedingly immature.
The antidote might simply be to challenge them to grow up by calling their bluff. Robert Bork, a former Marine, is an example of an intellectual who grew up.
I would agree accept that just getting a dose of thought not saturated in Marxism broke the spell for me (well, began the process.) I read THE FOUNTAINHEAD and ATLAS SHRUGGED and I was never the same again. That and 3 years of Free Republic was quite an eye-opener. I don't think psychological dysfunction could be undone so quickly.... could it?
But then, maybe I never was a true liberal. When I "came out" as an official conservative, my tree-hugging former friends all commented sourly that they had known that about me for years. (-:
