Why tho?
Anarchists think if we destroy all control structures, human beings will just hold hands and dance in a big circle celebrating friendship forever.
That’s a strawman.
It’s a lot harder to imagine a world governed by non-hierarchical structures than it is to imagine one more similar to the current one, infested with hierarchical structures.
And it’s easy to see anarchists as simply destructive since we love to talk about tearing down these oppressive structures, but people (and some anarchists) tend to forget that anarchism is also about building new systems. Some people tend to operate in the break shit then build shit mindset, but a lot of modern theory is about building the new in the shell of the old as a revolutionary act.
Plus, anarchism is not the “opposition of control structures” it is the opposition of hierarchical structures, which is different.
The Zapatistas are an anarchistic group that have existed since the 90s. While not “pure anarchism,” something they never sought out to do (they follow Zapatismo, their own ideology), they are very anarchistic in structure. And to think that a system that currently exists is impossible is just silly.
Cops are the legalized thugs of the state, the violent arm of private property. They are the natural enemy of all active left organizers, being the people that will actually shoot you when you do work against capital (including against cops themselves). This runs a wide range. They break up strikes by union workers. They shoot protesters. They arrest those who do direct action against particularly oppressive projects like the Keystone Pipeline XL. They harass anyone that looks a certain way. They enforce evictions.
Matapocos was a street dog that attended protests in Santiago Chile and bit cops because they attacked protesters. He was reportedly then semi-adopted and taken care of by left organizers.
