"Revolutions generally reflect the irresistible impulse for necessary changes which have been held back by official policies or retarded by social apathy. The institutions and practices of democracy provide ways and means by which such changes could be effected without recourse to violence. But change is anathema to authoritarianism, which will tolerate no deviation from rigid policies. Democracy acknowledges the right to differ as well as the duty to settle differences peacefully. Authoritarian governments see criticism of their actions and doctrines as a challenge to combat. Opposition is equated with 'confrontation', which is interpreted as violent conflict. Regimented minds cannot grasp the concept of confrontation as an open exchange of major differences with a view to settlement through genuine dialogue. The insecurity of power based on coercion translates into a need to crush all dissent. Within the framework of liberal democracy, protest and dissent can exist in healthy counterpart with orthodoxy and conservatism, contained by a general recognition of the need to balance respect for individual rights with respect for law and order."
