On July 7, CNN fired its senior editor of Middle East affairs, Octavia Nasr, after she published a Twitter message saying, “Sad to hear of the passing of Sayyed Mohammed Hussein Fadlallah,” one of the most prominent Lebanese Shiite spiritual leaders who was involved in the founding of the Hezbollah militia. Nasr described him as “one of Hezbollah’s giants I respect a lot.”

I find Nasr’s firing troubling. Yes, she made a mistake. Reporters covering a beat should not be issuing condolences for any of the actors they cover. It undermines their credibility. But we also gain a great deal by having an Arabic-speaking, Lebanese-Christian female journalist covering the Middle East for CNN, and if her only sin in 20 years is a 140-character message about a complex figure like Fadlallah, she deserved some slack. She should have been suspended for a month, but not fired. It’s wrong on several counts.

To begin with, what has gotten into us? One misplaced verb now and within hours you can have a digital lynch mob chasing after you  and your bosses scrambling for cover. A journalist should lose his or her job for misreporting, for misquoting, for fabricating, for plagiarizing, for systemic bias  but not for a message like this one.

What signal are we sending young people? Trim your sails, be politically correct, don’t say anything that will get you flamed by one constituency or another. And if you ever want a job in government, national journalism or as president of Harvard, play it safe and don’t take any intellectual chances that might offend someone. In the age of Google, when everything you say is forever searchable, the future belongs to those who leave no footprints.
