Put simply, the university is not the voice of expression, but the forum for it. The voice, or according to the Kalven Report, the “instrument of dissent and criticism,” belongs to the individual faculty members and students.
Consider the wisdom of these ideas as applied to the current Israel-Hamas conflict as a case in point. If a university issues a strong statement in support of either side (ostensibly expressing the voice of a majority of faculty and students, though not necessarily so, and rarely with unanimity), the contrary minority view is set at an automatic disadvantage.
