The trial dragged out arcane details of the scrutiny Churchill received leading up to his firing in 2007. Members of the Board of Regents admitted they launched the probe out of concern about possible “anti-American” sentiment in Churchill's writings and speeches. The decision to dismiss Churchill reportedly went against the recommendations of the university's Privilege and Tenure Committee, which called only for Churchill's suspension.

The evidence suggests that Churchill did engage in some sketchy scholarship. But its doubtful that issues taken up by the committee—for instance, a supposedly weak argument that the U.S. Army deliberately infected Indians with smallpox—warranted Churchill's firing. Stanley Fish noted on his NY Times blog, “if the standards for dismissal adopted by the Churchill committee were generally in force, hardly any of us professors would have jobs,” and asked,

"Had the governor not called [university president Elizabeth] Hoffman, had state representatives not appeared on TV to call for Churchill’s head, had commentators all over the country not vilified Churchill for his 9/11 views, would any of this have happened.? The answer seems obvious to me and it has now been given authoritative form in the jury’s verdict."

Churchill may not be the poster child for academic censorship, but his example is one of several that exposes the constraints professors may face when countering mainstream political orthodoxy.

Middle East studies has produced even more complex politicization of the academy. DePaul University professor Normal Finkelstein, a well-known critic of the Israeli government, was denied tenure and resigned after a long battle with the administration.

Nadia Abu El-Haj, a Palestinian professor of anthropology at Barnard College, came under heavy political fire when she was considered for tenure, because her scholarship challenged popular assumptions about Israel's territorial claims. Abu El-Haj was ultimately granted tenure despite an online smear campaign.

In a commentary in the magazine of the American Association of University Professors, Dan Rabinowitz and Ronen Shamir wrote, “like an American citizen who is arrested for the offense of 'driving while black,' Abu El-Haj seems not to be forgiven for her sin of 'writing on Israel while Arab.' "

Intellectual attacks may not have the same sting as racist police practices, but the academic world should be the one place free thought is allowed to flourish. If politics can undermine the most cloistered community of ideas, imagine the ideological hostility that stalks our public schools, workplaces and neighborhoods. Think at your own risk. Please.
