I don’t mean “idealist” as an arbitrary pejorative. I’m talking about idealism vs materialism as a way of understanding and changing the world. I’m not sure how far along you are in your journey as a Marxist - are you familiar with historical and dialectical materialism?
Do you live in the Imperial Core? I know you have “commie” in your username - do you consider yourself a Marxist?
Your question was about the feisability of mass moments. Mass movements coalesce due to material interests, are made possible through class consciousness, and are fueled by the blood and sweat of the people willing to put in the work to fight for unity.
I don’t know if “these people” you speak of are the reactionaries or absolutely everyone in the Imperial Core, but idealist notions of “paying for your sins” aren’t what make these movements happen.
The “go outside and organize” side.
