There’s a really good reading guide in the sidebar of this community, and Cowbee has their own here: https://lemmygrad.ml/post/6218252
I recommend reading through them, because they will cover everything you’re thinking about.
As a quick answer, though:
For those of us living in the USA discussing theory won’t change anything.
Marx himself said “The philosophers have only interpreted the world, in various ways. The point, however, is to change it.” and virtually everyone here will agree. However, if you don’t understand the theory then how on Earth can you challenge capitalism? You will be doomed if you do not understand how to apply dialectical materialism to your own country. Marxism isn’t a dogma, that’s why theory is so important.
How should we unite all of the different leftists under one leader so that there can be a united opposition.
You will never get everyone to agree fully, but you can get most people on board by talking about the problems and showing how Marxism can be a solution. If you want to unite people, go spread the word.
Currently we need far more comrades like Luigi to remove the bourgeoisie with violence.
Randomly popping off a capitalist doesn’t actually fix anything you know? They’re just replaced by another capitalist. The system itself needs to be removed. That can only happen when the working class achieves sufficient class consciousness.
@[email protected] gave an excellent reply so rather than reiterate what they said, I recommend their comment to understand why you can’t just pop off capitalists and expect change.
Really truly, although it might feel counterproductive the best way forward is to sit down and read.
