Why defenseless? The entire organization can defense itself from outsiders. No need of hierarchy for that.
Actually, there seems to be a bit of a mix-up. Let me clarify.
In an anarchist group, enforcing anything goes against its fundamental principles.
If personal gain is the motive, one isn't truly aligned with the group's social contract and isn't considered part of it.
Decisions are made collectively, without hierarchy. Voting or delegating organisational tasks to sub-groups is the norm.
I won't go into words like "attacking," "defense," or "threats" as they are military terms, far from the anarchist ethos.
And I won't call you "bro" or make you read theory. I feel you won't.
Anarchy is not by nature disorganized. Lack of hierarchy doesn't mean lack of organization. Probably a well-functioning anarchist organization is better organized than most hierarchical ones.
If friends are not there to defend the group of three, mutual aid is missing. That's why it failed.
Unions are not just for getting higher wages. They're not even just for when conditions start to get worse. Unions should be there for the best as well as the worst working conditions. Unions serve to maintain good and improve bad conditions, it's not about going against the "boss", it's about actively or passively defending the workers' conditions.
Would you trust your boss' lawyer saying "the trial will be fair, you won't need a lawyer"?
Wow, that would be the last straw. You have a link to his comments?
