> No we don't. There are laws against certain symbols etc ... the limit is in actually trying to overtake the state and abolish the constitutionYes you do. A core part of Nazi ideology was the Führerprinzip. They openly did not agree with the concept of democracy. If you don't talk publicly about your desire to overthrow democracy then you aren't a Nazi, it's as simple as that. The AfD do not want to overthrow democracy, therefore, they are not Nazis.
> It was a court case - but the court decided to drop the case
Do you understand the difference between prosecutors and the court? Because it feels like this understanding is missing here. None of the sources I can find mention the courts at all. There was going to be a prosecution of someone who insulted Höcke and the prosecutors - who are not the courts - decided not to, citing their own politically biased opinions.
But if the prosecutors don't prosecute, it never goes to court and never becomes a case. Right? The opinion of prosecutors has no legal weight whatsoever, that's the whole point of having courts in the first place.
> Or do you have another explanation why he wants to turn 180 degree in the view of the 3.Reich?
You've assumed he does, but that isn't obvious at all.
I would assume that if he objects to both allied and Nazi bombing being a war crime, he just doesn't accept that the concept of a war crime exists at all. This is a very common perspective outside of the left, because the notion of a war crime assumes there is such a thing as international law that makes it a crime, which in turn assumes the existence of an international government that can make and enforce such law. But there isn't any such government, therefore international law does not exist, therefore there is no such thing as a crime that countries can be found guilty of.
The left doesn't like this idea, they're big fans of the idea of world government and thus tend to enthusiastically support courts who pass "judgements", even when they aren't enforceable by anything.
I find both perspectives understandable. People on the left often don't, which is why you extrapolated from his position into assuming he must be a Nazi.
