It won’t always be the same ones so I’m unsure of what you’re asking. Which ones invaded the spaces I listed before?
For Revolutionary Catalonia it was the Nationalist Faction who overthrew them. They advocated for, and implemented, a form of national syndicalism that was “fully compatible with capitalism”.
For Red Vienna is was the fascists who overturned the socialist policies and returned the city to a state of capitalism, allowing land-leeches and other bourgeoise to return to continue exploiting the working class.
You really think “part of nature” is a good argument for if something is morally acceptable? You can’t think of anything that happens in the natural world that we choose not to do as civilized moral agents because it’d be wrong to do?
