No. I barely have the emotional bandwidth for this and I'm on the wrong device for a long form comment but let's give it a try.
East Germans got fucked by annexation. For a long time PDS/Die Linke did well in the former DDR states, but they never stood a chance at national power since capitalist West Germany cannot tolerate socialism. And why would you vote for the same party for over a generation when they never get into power and nothing improves for you anyway? The "mainstream" parties were the people who looted the East and ignore their material struggles while being very condescending, so they have almost no support. Then come the AfD, an opportunist party of fascist grifters no doubt, but one which saw the struggles and frustration of East Germans and spoke to them. Not at them, not down to them, but to them. They don't have solutions but they at least speak to the situation of the East, and thus they have developed a base of support.
So yes, the AfD grifters pretend to have Natalie and wave DDR flags to get votes, and many people who really have Ostalgie and may have voted Left ten or twenty years ago now vote AfD, because their material conditions have put them in a really shitty place.
If you're interested in learning more about the DDR and the fall of socialism in Europe I can recommend the books "Stasi State or Socialist Paradise" and "Blackshirts and Reds".
In general equating the DDR with fascism and the Nazi state is a tired old capitalist propaganda trope which unfortunately far too many people still believe even though it is a complete logical fallacy. There are plenty of resources on Lemmygrad to completely annihilate that concept.
