No, both can be true at the same time. Most liberals know much about their favorite spectacle (celeb drama, idealist politics, religion, etc) or fandom (Harry Potter, Star Trek, and so on), but they don’t know what matters, the nature of the society in which we live, the solutions to societal problems, and other things that a dialectical materialist worldview brings to light. They are knowledgeable in things the ruling class allows them to be, yet they are still ignorant. People can also be knowledgeable in things like science or life skills that are valuable, but they still would vastly benefit from Marxism.

I see what you mean and I agree, libs aren’t blank slates that can be taught about communism plainly. They need to first unlearn a lifetime of red scare propaganda before they’ll be receptive to a Marxist education. They’re not simply ignorant, they’re misinformed.
