A Communist should have largeness of mind and he should be staunch and active, looking upon the interests of the revolution as his very life and subordinating his personal interests to those of the revolution; always and everywhere he should adhere to principle and wage a tireless struggle against all incorrect ideas and actions, so as to consolidate the collective life of the Party and strengthen the ties between the Party and the masses; he should be more concerned about the Party and the masses than about any private person, and more concerned about others than about himself. Only thus can he be considered a Communist.
--Mao Zedong
“ The reformists have a good smell for what the audience wants… But that is not serious revolutionary activity. We must have the courage to be unpopular, to say ‘you are fools,’ ‘you are stupid,’ ‘they betray you,’ and every once in a while with a scandal launch our ideas with a passion.
— Leon Trotsky, “Discussions on the Transitional Program,” 1938
