I don’t mean posting or vague things like support the anti imperialist countries. If you work with capitalists they always talk about scale. What can we do that practically “scales” while staying in the lines enough to not meet the FBI’s dungeon and dragons team?
Posting is actually a practical step itself. It's just that, as you've pointed out, that also needs to scale. We don't have an equivalent apparatus to the established media with which to counter narratives. So the only thing that seems to have a shot beyond another lucky George Floyd tier uprising is the traditional ground game where we have to talk to people IRL. Actively spreading anti-imperialist, communist tiktoks within your family and friends groups could be a good first step.
