>> At no point during that parties history was it ever 'left-wing'
What?! Of course it was - history time: the small feller with moustaches joined an anti-capitalist workers party. It's in the name - it was socialist but nationalist so anti-communist but still decidedly to the left of say the DNC today. Check the manifesto including things like banning rentiers, seizing land, obligating pensions and this little gem "We want all very big corporations to be owned by the government" etc. The moral is that its not where you start, its where you go that matters.
You are completely ignoring the part where he effectively replaced the core of that insignificant political party during the takeover. It's incredibly deceptive to conflate the single most conservative movement in history with leftism because of a hostile takeover of a tiny political party. If you actually read those 25 points, it's a blueprint for a regressive totalitarian dictatorship with a command economy. If you consider that 'leftist', then I couldn't disagree more.
The Nazi party had a left wing well until just before Hitler was appointed chancellor, when it started causing problems for the man and he had it purged. (A lot of the leaders of this wing of the party were killed in the Night Of The Long Knives.)
