I am searching the source and exact words for a quote from Hannah Arendt that I only vaguely remember:
Das Ziel totalitärer Systeme ist es nicht, die Menschen von der eigenen Ideology zu überzeugen. Vielmehr sollen sie unfähig sein, eigene Überzeugungen zu entwickeln.
The aim of totalitarian systems is not to convict you of an ideology. Rather they want to make you uncapable of having a belief.
Maybe, the news article that quoted Arendt did not cite her exact words but was referring to this quote? (Update: The below quote is easy to find. I'm searching for sources for the above quote!)
The ideal subject of totalitarian rule is not the convinced Nazi or the convinced Communist, but people for whom the distinction between fact and fiction (i.e., the reality of experience) and the distinction between true and false (i.e., the standards of thought) no longer exist.
