Where there is much truth in what you list, one need also see another aspect.
Namely that in the GDR there was nowhere near as much education on the German Nazi past as there was in the Western Federal Republic.
Education, that is, of the kind that showed a whole nation or, at least, a substantial majority of it, as having fallen to the Nazi rat catchers and thus most Germans could logically not be excluded from bearing responsibility.
All of this stressing the "hereafter" responsibility of everyone to not let that happen again.
The GDR took the easier way of locating all Nazis "as in the West", thus exempting all East Germans from ANY responsibility, seeing how it comprised "good communists" who thus couldn't possibly have a Nazi past, let alone future.
This is also now coming home to roost especially in East Germany.
Add the fact that the much hated regime itself was no longer the available address to which to send one's gripes, and psychologically replacing it with the then new Government was not a far step.
Western Nazi types saw fertile ground which to conveniently occupy and moved fast.
They immediately recruited AfD "brawn" while supplying the "brains" themselves.
Weidel is West German, Gauland is, Höcke is and practically the whole rest of the leadership is from West Germany.
In fact the whole party was founded in West Germany, but had completely different aims then, in the meantime having been undermined by the fascists from West Germany who saw their far more promising career chances in "the East".
On the principle of "if you want to gain power, you need to apply for it where the greater amount of easily led fools resides."
Parallels to your current leadership being purely coincidental.
