Can you build a car without a chassis? No. But if you have a chassis and nothing else, all you have is a piece of useless metal.

Memes, social media, forums, podcasts, videos… this is how you reach a lot of people (but not everyone) in 2023. It’s an important part of building a movement. But it’s just one part that’s useless unless combined with the other parts - organizing, understanding theory, applying both those to local conditions, etc etc.
