lolno.
Too many guns and too many rednecks.
Plus, the muslims that have been here for many, many have a long, long history of being well assimilated and generally tolerated in their communities--which lies in stark contrast to the history of immigrant communities in European countries and cities--basically the remnants of colonial experimentation and only allowed into those countries so long as they they remain "in their place." That had been going on for well over a hundred years now, with generations of outright prejudice and refusal of access to host country values, culture, services.
The USA has a long history of treating it's immigrants better, in comparison (obviously some very real dark times--not to discount any of the anti-chinese, irish, italian presence from generation to generation), but still, all of those communities assimilated. Hell, muslims have been in remote parts of Wyoming for well over a century and had established themselves for generations--probably alarming to some.
Of course there will be some problems here and there, but a lot of what seems to be happening with these loan wolf fucksticks in the USA claiming whatever they want to claim is an evolution of privileged suburban teen-angst, that really isn't that much different from the sort of kid that wants to shoot up schools for their own reasons. It's a problem that is very difficult to address, whether you call it bullying or Islamic extremism that lead to it, no matter what community you are dealing with.
The USA does not have sharia neighborhoods, and never will. We will certainly be dealing with the same type of jihadi-wannabee ostracized teens looking to wreak havok for whatever purpose they claim, but outside of blocking the internet for "suspect groups" (hello laws) or physically and digitally tracking "suspect groups" en mass, (oh yeah, laws again), there is only so much that can be done.
