This thread has gotten so off topic it must be realigned.
I think Islam, and by extension any other culture, is only a problem when it comes to a foreign country and then tries to remake that country in its own image. I classify these immigrant populations as "invasive movements," instead of "assimilating movements." From what I have observed, Islam in Europe has been trying to assert itself through intimidation, crime and lobbying. I have read studies and articles showing that Islamic immigrant populations commit high amounts of crime, rape, and murder disproportionate to the native population, and I have also seen how Islamic immigrants attempt to shape the social and cultural landscape of their new "home" by rioting and attempting to change the laws to suit them.
It's almost like the illegal Hispanic immigration problem we have in the American Southwest, with the exception that Hispanics (Mexicans, to be exact) had a foothold here until we drove them out 150 years ago, so I suppose the Reconquista has some air of legitimacy. Of course, they also share the other traits of the invasive movement of Islam by heightening crime and urban decay, but that's for another thread.
All in all, Islam should be put in its proper place as just another religion before it does some actual damage to the sociopolitical landscape of Europe. They're already quite cocksure as it is.
