Honestly, this is why using only a left-right axis to describe politics is inadequate. If the term wasn't prestressed, BSW would be literally National Socialist (but please don't use that term, because, you know, Hitler, and she's far from that).
Oh and BSW being a SED clone is regarding Wagenknecht being a SED politician and her very close ties into the Kremlin.
That's oversimplifying if I've ever seen oversimplifying. To the point of disinformation. Wagenknecht wasn't allowed to study because she clashed with the regime, was accused of a hunger strike during military training and joined SED *half a year before the Wall fell with the intention of reforming it. And licking Putin's boots is not enough to be an SED clone.
