I guess a lot of it depends on how personally one takes the perceived insults. Who are the other European filmmakers famous for insulting us?
I've read a lot of interviews w/ Lars and I get the impression his films are mostly about human flaws magnified - he just enjoys reminding Americans that we're human too. It's the people he highlights, not our democracy or whatnot.
Mostly, I just enjoy any opportunity to see Nicole Kidman's or Bryce Howard's naked breasts
Even if it is in odd or (so-called) unpatriotic films.
I'm not just talking about filmmakers who insult Americans. Even though a lot of them take subtle jabs, but they make interesting points.
And I don't have any links to give you of Von Trier, but I remember distinctly an interview in Entertainment Weekly where he famously said he refuses to step foot in America. And I'm okay with him having a problem with our foreign policy or whatever.
My problem comes from his strange, contrived, delusional take on American community.
The rape scene in Dogville for me was the breaking point for me. I just couldn't take him seriously anymore after that.
What's sad is that he has the potential to be a visionary and has shown it in work like his original Kingdom Hospital, Breaking the Waves, and even the bizarro America depicted in Dancer In the Dark.
But his Grace trilogy? It's really a study in sadism, which in his mind he links to American society.
