What a strange idea for someone from Germany. Here you are registered as a citizen and get a letter to your registered address and you take that to the voting station. Vote. Done.

Was it just an expressed opinion of "Germany was most of the time undemocratic, unfair and discriminating"? Yes, it wasn't democratic in the Kaiserreich from 1871 until 1918, it had huge democracy deficits in the Weimar republic from 1918 to 1933, it was a murderous, facist dictatorship from 1933 to 1945, and a Russian puppet state with fake elections from 1945 to 1989 in the East. So I would agree with that expressed opinion.
