Lol. I never said National Socialist was left, I said BSW is not left. It is not considered left in the german political landscape (except by right wing nutjobs like AfD).
I got my political knowledge straight, you're making stuff up.
BSW has too many positions that are not considered left (their stance towards migration alone is all but left). And where are it's authoritarian positions?
You're throwing around a lot of terms that don't mean what you think they mean.
