This article explains what organizing is and where some of the confusion in terms comes from: https://clarion.unity-struggle-unity.org/2024-06-06-what-is-organizing/
I also like gramsci’s essay here on building the institutions that will replace the bourgeois state: https://redsails.org/democrazia-operaia/
Unionise, strikes, mutual aid, and other forms of collective action that leverage the power of a group of people to their benefit.
Fights though? Where did you get that from?
People’s Army
Community defense isn’t about “doing fights” and nearly anything else you might mean is just adventurism (bad)
Wait, isn’t the point of creating a people’s army to fight on a revolution?
We need infrastructure, General. Making a revolutionary army is the job of communist party, not militia adventurists or larpers. Jumping to “revolutionary” violence is putting the cart before the horse. If you want to shoot guns, join an SRA branch or whatever. If you feel like your only use is killing people, seek counseling.
