Do you believe we can achieve those systems with our current world order? (Liberal-facsism)
Yes. But only in the chaos caused by the disasters this world order itself inflicts on the world.
How do you implement direct democracy and scale it without interference from the capital class?
You can't. It has to be done with the understanding that the capitalist class will do it's utmost to destroy you.
It is only a matter of time before pigs or some paramilitary pig-wannabes perpetrate a massacre of protestors in the US.
When (not if) they do, watch out... it will be open-season on anybody that's marginalized or slightly left than Heinrich Himmler.
I sure hope you all are ready for this.
