Yeah, right. Given the sick demonization of Americans rife in German media and society (most recently, American businesses were compared to a plague of locusts!), I have no doubt this is meant as just another petty insult from the oh, so morally superior descendants of the Nazis...

that a german civil court would pay special attention
to the very ordinary working day 4th of July.
And when it comes to insults, you are an expert, no doubt
about that.
