I’m east German and, although I can confirm that this sentiment is widespread (which is lovely by itself), you do have to note that a lot of this defense are merely people who are disputing the insane wrong claims that are brought forward by media. They usually defend some sort of position that both the former government and the current one have had their advantages and drawbacks and at least quite a few of the people that I know would not necessarily take part in a hypothetical revolution to bring back the GDR.
