"It also important to distinguish between class background and one’s own performance, with emphasis on the latter. The exclusive component theory is incorrect. The question is whether you take the stand of your original class or take a changed class stand, that is, taking the side of workers and poor and lower-middle peasants. Moreover, you are not supposed to engage in sectarianism, but must unite with the majority, even including some of the landlords and rich peasants, as well as their children. There are some counter revolutionaries and saboteurs who should be transformed, and if they wish to transform, we should have them, one and all. But if we consider only the background, then even Marx, Engels, Lenin and Stalin would be unacceptable."
