To let things slide for the sake of peace and friendship when a person has clearly gone wrong, and refrain from principled argument because he is an old acquaintance, a fellow townsman, a schoolmate, a close friend, a loved one, an old colleague or old subordinate. Or to touch on the matter lightly instead of going into it thoroughly, so as to keep on good terms. The result is that both the organization and the individual are harmed. This is one type of liberalism.
To indulge in irresponsible criticism in private instead of actively putting forward one's suggestions to the organization. To say nothing to people to their faces but to gossip behind their backs, or to say nothing at a meeting but to gossip afterwards. To show no regard at all for the principles of collective life but to follow one's own inclination. This is a second type.
