Michael, having a German heritage doesn't make you German and your name makes you a jackass. If I get banned for saying Michael's a jackass I'm gonna be pissed because his name is an affront to 50 million people (in Europe alone) that had to die during WWII because a couple powerful dictators decided to play hardball.
Why do germans hate hitler?
Well, we don't even know the guy, but thanks to him Germany was torn to pieces, divided into 2 separate countries for almost 50 years and we're still recovering from the social-political-economic damage done from WWII. Not to mention we were the center of every Hollywood war movie from the 1940s onward until terrorists finally took over the stage. Oh yeah and the fact that no matter where I go in the world the first thing people say about me when I tell them I'm German: Oktoberfest, BMW, Hitler.
Fridge, the only thing about the clan that would be considered illegal is their tagline. Oh and the players who calls themselves Hitler and Fuhrer (it's spelled Führer by the way, I've had to correct them on all their German so far), but they're not in Germany, so nothing can be done. Actually, I don't think it's against the law to call yourself Führer, because you can't prove it actually refers to Hitler...
BTW, Hitler was Austrian. That will be all.
