Ackman, in his initial tweet about Harvard, said that "a number of CEOs" shared his desire to publicly out the Harvard students who condemned Israel. Other business leaders were quick to echo his calls, winning plaudits on social media. In a visit to Harvard, Insider spoke with a range of students about the backlash to the statement on Israel. It's ironic, of course, to accuse students of silencing dissent when Ackman and other business leaders are seeking to do exactly that. But now, some Harvard students fear that the backlash from the business community will have a chilling effect on student speech.
