Here's a real antihero! As far as I’m concerned the following sentence from GAWKER summarizes this guy: “Martin Peretz is an obscenely wealthy moral cripple who owns the New Republic.”
Peretz married a very rich woman when he was in his 20s, and bought influence and access to power in various ways, eventually using the New Republic to further his ends. While he did hire accomplished left-wing editors to run the magazine, his contribution seems to have mainly been curmudgeonly comment becoming more and more grumpy and neocon over the years. I can’t imagine why three or four major publications devoted huge amounts of space to him in December and January of last year, but they did. Hero or anti-hero? Who cares. Secular Jew? Yes, but who cares? What’s so great about buying your way into fame and influence?
