Unanimity rules protect minorities by violating majorities

Evidence

Yet the contradiction between cooperating in a collective action and opposing it as an individual, does not, in itself alone, entail the logical consequence of unanimity. For if a proposal, for lack of a unanimous vote, is considered rejected, the minority (to be sure) is thereby prevented from being violated by the majority but the majority is also violated by the minority. — Georg Simmel, The Sociology of Georg Simmel, 6145

• DEFINE: Crisp statement of the symmetry behind unanimity rules—the majority is itself a party that can be injured.
