Just thinking that you ought to have those kinds of laws doesnt mean applying them wont result in a tragedy.
Edit: Might have misunderstood your reference. The KPD NSDAP dynamic is often referenced as the "verängstigte Bürgertum". It was quite the popular reference during Pegida, but it has been a common explanation since it happened and isnt just a modern take. The coups during Weimar, and the political reactions to them has to be seen in that light as well. Can recommend Heinrich Hannovers "Politische Justiz 1918–1933" on the atmosphere of the time.
Edit1: His "Die Republik vor Gericht 1954-1995" is also something i would recommend reading for a more realistic view of Western Germany. And Ingo Müllers Furchtbare Juristen. Might be worth reminding people that actual nazis got quite the nice treatment till very recently. The current wave of prosecutions against KZ guards is a historical abnormality, unless the allies actually hung you you got away with a slap on the wrist and in good social standing. Because you were needed against the Soviets. A AFD/CDU might get really bad, there were already CDU politicians during the burning refugee housings in the 90s that argued for more compassion for the drunk piss stained mob.
There was this great picture of a piss stained drunk doing a nazi salute during one of the Pogroms that i cant find on google and bing anymore. But luckily i dont have to worry about such things anymore because everyone means well.
