"history has shown time and again that second and third generation immigrants become diluted in their behaviour."
I agree mowibble, the first generation's traditions do rub off on their siblings and by the time the 3rd generation arrive they're more westernized and want to fit in. Only potential difference I see in this case though is if they remain in their religion (quite likely) the potential is there to become radicalized by it.
Fwiw, I have seen the videos in question on youtube and I have to say they are of very bad taste and imo appeared to have been made with the purpose of insulting the followers of that faith. I personally think youtube should remove them (if not already) and take a bit more responsibility for what gets uploaded.
