Anyone who sees through Howard Zinn’s warped vision of American history deserves some praise. As David Bobb writes in the Wall Street Journal, former Indiana governor and current Purdue University president Mitch Daniels is catching flak for his candid assessment of Zinn’s work product.

Upon the death of the Marxist-inspired historian Howard Zinn in 2010, eulogies rang out from coast to coast calling him a heroic champion of the unsung masses. In Indiana, then-Gov. Mitch Daniels refused to join the chorus and instead sent emails to his staff wondering if the historian’s “execrable” books were being force-fed to Hoosier students. The recent revelation of these emails provoked an angry backlash.

High-school teachers within Zinn’s vast network of admirers blogged their disapproval of the governor’s heresy, and leading professional organizations of historians denounced the supposed threat to academic freedom. At Purdue University, where Mr. Daniels now serves as president, 90 faculty members hailed Zinn as a strong scholarly voice for the powerless and cast the former governor as an enemy of free thought.

An activist historian relentlessly critical of alleged American imperialism, Zinn managed during his lifetime to build an impressive empire devoted to the spread of his ideas. Even after his death, a sprawling network of advocacy and educational groups has grown, giving his Marxist and self-described “utopian” vision a wider audience than ever before. …

… Before Zinn launched his own teaching career, he became a member of the Communist Party in 1949 (according to FBI reports released three years ago), and worked in various front groups in New York City. Having started his academic career at Spelman College, Zinn spent the bulk of it at Boston University, where on the last day before his retirement in 1988 he led his students into the street to participate in a campus protest. …

… In 2005, as a guest on Comedy Central’s “The Daily Show,” Zinn delivered his standard wholesale condemnation of America. Surprised by the unrelenting attack, host Jon Stewart gave the historian an opportunity to soften his criticism. “We have made some improvements,” the comedian asked, “in our barbarity over three hundred years, I would say, no?” Zinn denied there was any improvement.

As classes resume again this fall, it is difficult not to think that despite the late historian’s popularity, our students deserve better than the divisive pessimism of Howard Zinn.
