Then you should have no problem listing these similarities because otherwise
I have literally no idea what the fuck you're talking about. Germany is ranked 13th on the Democracy Index and scored 95/100 on the Freedom House Index. Your comparison to the GDR is absurd to say the least.
To make one thing clear: I'm not comparing the political system. GDR was a totalitarian socialist dictatorship. Modern Germany (and by extension the EU as a whole) is on the way to become a authoritarian neo liberal oligarchy with a few remains of social democracy sprinkled on top to make people keep their feet still.
Where i see similarities is in the ever increasing trend of mechanisms that shape public opinion and keep people in line with the government such as propaganda, surveillance, fear mongering, cooptation and denounciation.
News and coverage on public broadcasting and mainstream media is more and more opinion then information. And not any opinion but opinion that's in line with whatever the government does. The 2015 refugee crisis exposed this in a very dramatic way and yesterdays almost neglect or side note reporting about the NetzDG is only the latest example. Anyone still remember the other surveillance laws that passed just a week earlier? Where was the outcry? Our justice minister step by step puts a system into place that would make Stasi jeleaous. But hey, it's for a noble cause, right? Fight against the right wing and terrorism. Remember what the propaganda denomination for the inner German border was? Antifascist protection wall... Sounds familiar to me!
Another striking similarity is the ever more prevalent moral high horsing and patronization by the elites of society, politics and media. This one really gives me the creeps. Please go on youtube and watch some episodes of "Der schwarze Kanal" from GDR television and tell me the lecturing tone isn't similar to what certain politicians and "TV personalities" let off today.
Now about the political landscape. GDR had one unified party and a few puppet parties. We arn't there yet but certainly feels like the differences between the parties erode more and more. Angela Merkel did a great job to make left green positions her own. Anything even left now that gay marriage has been dealt with? The lefts and the greens on the other hand get caught parroting neo liberal positions like the fairytale about skilled workers. Living in Thuringia under red green government i could sing you a song about it. Some notable exceptions like Sarah Wagenknecht or Oskar Lafontaine but they are few of the oldschoolers that still hang around.
What realistic options do we have for the next election? It's either EU Angela or EU Martin. Talking about EU, here is a another similarity. GDR left a lot of it's sovereignty to Moscow. Modern Germany let itself governern from Brussels in large parts.
As for your democracy index, it's ultimately useless when the standards are so low. Explain to me one thing: How come the government in this supposedly so democratic country can push through a constitutional change in 48 hours without any public debatte yet an undeniably defacto authoritarian regime like Turkey lets its people vote about constitutional change?
You are falling for a meme my friend, the same meme that brought freedom and democracy to places like Iraq, Afghanistan or Syria.
