Partisan tolerance
Partisan tolerance is a concept invented by communist author Herbert Marcuse. Partisan tolerance dictates that the enemies of Marxist revolution have to be forced into tolerance, but socialists are allowed to be intolerant against them. This is because there are "correct" opinions that are to be preferred, and "incorrect" opinions that have to be fought against with all means.
According to Marcuse, a non-partisan tolerance would leave the established values intact, which would lead to repressive tolerance. Therefore, Marcuse only accepted a partisan tolerance which would have to be "intolerant toward the protagonists of the repressive status quo", or would promote "intolerance against movements from the Right, and toleration of movements from the Left".
