I’ve spent years arguing with people online and really have nothing to show for it aside from my own education and amusement. I was radicalized by discovering r/chapotraphouse back in 2018 I think. Nobody argued with me there, I just lurked, loved the memes, thought it was the funniest place online, then started reading theory because so many people there talked about it. Even though liberals are obviously ignorant about communism, their ignorance is willful: they never thank us for educating them, they always get angry and double-down. (In real life, it’s much easier to embarrass them and get them to shut up.) Still, I admit that it’s possible to change someone’s mind in an online debate, I just haven’t seen it happen when it comes to communism (libs on r/changemyview can change their minds about lib shit). Have you ever seen a lib admit that they were wrong about communism?
Most actual communists I know came to it on their own in their own time by personally seeking out more information to educate themselves about the world, not by getting into verbal dick measuring contests with randos on the internet. You've not ever gonna have much success "converting" people if they're not in the right place to be converted. I honestly think propaganda is only really effective when the people hearing already kinda agree with it, it just makes them agree even more. You can talk a baby leftist into being a grown up leftist but if someone is a diehard CHUD or Lib that ain't gonna change until something in their life makes it change.
