This is absolutely the way to educate. Don't tell them things, help guide them to conclusions, encourage them to think about and discuss the topic with you, give them information and ask Socratic questions about their understanding of things, always make it clear that these ideas are not a part of their personal identity, otherwise they'll just feel attacked and refuse to engage.

And it can take years of patience before someone really starts examining things closely of their own volition, you can't force someone to change their mind, you can only help them along the way.

The Socratic method takes multiple hours. I'm complaining about random little conversations with strangers in a gym or bar or whatever. Young people almost always self describe as socialists, but are really social democrats or whatever. I want to convince them to read theory in like a 5 minute conversation. So if I'm at the climbing gym and can tell the other person is a certain type of engineer tech bro, all I have to do is say lumpenproletariat or dialectic or something and they'll then read whatever essay I send them. That does only work on very specific types of people, most people get turned off socialism forever if you do that.
