Insurgent Notes: Journal of Communist Theory and Practice

That quote is from "The German Ideology", not "The Communist Manifesto"...

The Manifesto of the communist party was penned solely by Karl Marx and, "The basic thought running through the Manifesto belongs solely and exclusively to Marx", according to Friedrich Engels in 1883. The two men did not share an "intellectual bank account", merely a common stock fund.

Der Kommunismus ist für uns nicht ein Zustand, der hergestellt werden soll, ein Ideal, wonach die Wirklichkeit sich zu richten haben.
For us, communism is not a state to be achieved, an ideal to which reality must conform.

Wir nennen Kommunismus die wirkliche Bewegung, welche den jetzigen Zustand aufhebt.
We call communism the real movement that abolishes the present state of affairs.

Die Bedingungen dieser Bewegung ergeben sich aus der jetzt bestehenden Voraussetzung.
The conditions for this movement arise from the existing prerequisites.

Three glaring faults with the mast head. No wonder the hot air went out of its sails.

We insurgents should note the addition of wird, the German word for "will be", to the text of The German Ideology. It is reminiscent of the corruption of the First Letter of John by the addition of the verse, "in heaven, the Father, the Word, and the Holy Ghost: and these three are one", to fit in with the false teaching—the Trinity—promulgated by Christianity, for which many innocents lost their lives.

Wow, amazing, congratulations!
Their website looks down for me. Hopefully just a temporary situation
