I'm not German, but I can imagine how Germans must feel with the shadow of Hitler and the Nazis hovering in their historical background... Especially with so much fiction being based on the World War II. Take these comic book-based Hollywood movies that have come out lately, for example - I've seen at least two in the past months whose themes related to fighting the Germans and stopping Hitler (X-Men: First Class and Captain America: The First Avenger). I wonder how Germans are feeling going to the cinema and watching these movies only to see that the bad guys always have a German accent...
Actually the connection between X-Men, Captain America, and Nazi Germany is nothing new.
The original
X-Men's episode "Old Soldiers" aired in 1997 showing Captain America and Logan in Nazi Germany teaming up to stop the Red Skull. It isn't a new idea that Marvel would include the two in such a mission, both great heroes, both alive during the war, both experimented on to become super-soldiers; I always thought it was a great plot. It's included in the history of both heroes in each animation:
The Avengers, X-Men Evolution and
X-Men the original series, as well as the comics. I think Hollywood's done a pretty good job with that, aside from the fact that they made Logan fall in love with Jean Grey when in actuality Logan marries Storm and Scott marries Jean. And Logan didn't kill Jean and Jean didn't kill Professor X! I also thought that last movie,
X-Men: First Class was a head shaker. I refused to take part in that movie; in no way was any of that movie even close to accurate!

As far as how Germans feel when watching those types of movies, I'd suppose that if they didn't like how they were portrayed they wouldn't watch them. I'd imagine they would feel the same way white people feel when they watch a movie like
Roots or how Japanese people feel when they sit through
Pearl Harbor. It's a part of history that can't be erased. There's no reason to burry your head in the sand and feel offended every time someone asks a German questions about Nazis just like there would be no reason for a white person to be offended if someone asked them if their ancestors had slaves. History is history, there's no use being imbarrased about the mistakes that our ancestors made, hopefully people remember those mistakes so as not to make them again in the future.
