You beat me to it. Those wacky, fun-loving French "youths".
Despite what has happened over the last 20 years, European cultures are not exactly known for their acceptance of other cultures. "Celebrating Diversity" is not something that comes naturally to them. I'm wondering how long this will go on before the locals rise up and give these "youths" a formal beat-down.
Hmmm. Then again, European history is littered with examples of one empire or another conquering and ruling for several centuries. Occupation and servitude may just be another form of government to some.
They'd better hurry up; the families of these "youths" are outbreeding them three or four to one!
