I'd like them to try this nonsense in Germany - they would have a lot of fun with the police and the justice system, who really don't like people to do things like that. (That is assuming that they didn't manage to get themselves beaten up by radical antifascists before.)

That aside, as a German, I can't even express how offended I am by people "playing Germany" (or whatever they think they are doing, I wouldn't touch the canon material with a ten-foot pole after seeing the fans) by glorifying the exact same things that we are still struggling with. My parents were toddlers at the end of the war, and I'm still always nervous about disclosing my nationality online or on journeys abroad, because you never know what people will ask/assume/accuse you of.
