Robert Paul Wolff, Barrington Moore, Jr., and Herbert Marcuse, A Critique of Pure Tolerance (Boston: Beacon Press, 1969), pp. 95-137.
Marcuse argues that "the realization of the objective of tolerance" requires "intolerance toward prevailing policies, attitudes, opinions, and the extension of tolerance to policies, attitudes, and opinions which are outlawed or suppressed." He makes the case for "liberating tolerance", which would consist of intolerance to right-wing movements and toleration of left-wing movements.
