We stand for active ideological struggle because it is the weapon for ensuring unity within the Party and the revolutionary organizations in the interest of our fight. Every Communist and revolutionary should take up this weapon. But liberalism rejects ideological struggle and stands for unprincipled peace, thus giving rise to a decadent, philistine attitude and bringing about political degeneration in certain units and individuals in the Party and the revolutionary organizations.
Liberalism manifests itself in various ways.
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.
