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?
That precisely is the problem - any large enough and as such powerful enough organization poses a threat and it doesn't matter if you follow the law, your existence becomes reason enough to repress and destroy you.
Though still there is a lot that can be done as the power of the hegemon isn't almighty.
