Liberals on Lemmy.world are ideologically wrong. Lemmy.ml is also made up of largely working class people. Mao's point is not that anything that is popular is correct, but that the working classes better understand the world through direct practice, life-activity. The conflict between Lemmy.world and Lemmy.ml isn't because communists refuse to see the wisdom of the working classes, but because in areas where liberals and communists disagree, the liberals are incorrect. Wisdom comes from the working classes engaging in direct practice, yes, but this practice needs to be guided by correct theory, otherwise it's just vulgar empiricism rather than dialectical materialism.
