I mean, you definitely should read theory. Summaries are helpful, as are cool ways to explain complex concepts, such as dialectics4kids when it comes to teaching dialectical materialism. However, advanced theory is helpful for accurate analysis and advanced practice. It better informs us on our conditions and our necessary tasks in building a better world. I made an introductory Marxist-Leninist reading list to help facilitate that process of learning, and to help expand my own knowledge to help my IRL organizing.

When we reject theory, and reject advanced analysis, it's akin to a factory abandoning best practices and doing whatever feels best at the moment. Such a factory would probably work fine at first, but would run into far more hiccups, accidents, slow production, and even fall apart. So too do revolutionary projects need accurate analysis, best practices, and a solid understanding of the forces at play that go beyond simple vibes.

Revolution is like designing a smartphone, you need to analyze social development, its behavior and laws, history and trajectory, just like you need to analyze material science, physics, electrical engineering, chemistry, and more, not to mention logistics, shipping, mining, packing, and more to develop a smartphone.
