People think of anarchism as against organizations and rules, but its just against hierarchy. Western people in particular are so used to hierarchical thinking that its difficult to even imagine an organization that isn't hierarchical in nature.

Hierarchy is “Western” now?

And "eastern culture" is largely not hierarchical by heart?

Also, I have been to quite some anarchist places, but I did not found one without a hierachy. It is usually just informal. (But at times even formal and everyone pretends it is still not hierachy)
