You can easily look up the answer to your question by yourself: leftist theory, often in the form of books (or even just watching video essays, listening to podcasts etc. etc.)

One could argue that there are too many different socialist approaches to revolution or rather that it's not all that easy finding the correct one to your situation

... revolution. That is the idea. We are talking about two completely different things, you expect run-down people to think logically and clearly about something as complex as an alternative*(edit) societal system while actively existing in some of the worst social contexts we've seen in decades, while we are talking about acting in such a manner as to free up the cognitive bandwidth necessary to determine what you demand.

It's like any other toxic relationship, you can't begin to heal until you've exited said relationship.

To clarify, by any means necessary. Start demanding, start opposing, start rallying. Spread the word, keep the reality of things alive in people's awareness, because the natural instinct is to retreat and deny in order to protect oneself, but that's exactly the trap the Right sets and then springs for a massive boost in support from downtrodden, desperate people.

Edit to add: the Right and Capitalism, because they both infiltrate and exist by solving problems they themselves create, thus garnering support through necessity.
