College presidents can change the hostile environment on campuses

Jewish students are afraid to speak and genuinely fear for their safety, says Frida Ghitis .

Ghitis: Campus culture leaves little space for voices to question and challenge the views of those who are most vocal.

She says it is their job to create a campus culture that protects speech and promotes robust debate and dialogue.

These administrators not only police speech and expression, but try to define the terms and context of speech itself and they are the source of so many of these problems. Colleges are in crisis; we must demand change quickly, and it is not too late for presidents to have an impact. Samuel J.
