I live in New York City, where there are more Jews of all sects all across the political spectrum than there are all people on Copenhagen.
You live closer to those regions, so you get the low level members of their society by default. We have a few of those too, they try to emulate rappers and do dumb shit. Literally a part of every culture.
I don't know what you want me to say though, to try to compare with Jews by saying things like Hasidics have lived here for generations and can't even read or write, let alone speak English? Or how Orthodox sects will essentially colonize entire neighborhoods by pushing people and their businesses out in favor of their own? I've watched with my own eyes how the administration of my college, located in a Jewish neighborhood, catered to everything they wanted while simultaneously trying to stop every little event that the SJP group was doing. They can't invite any speakers, meanwhile it's perfectly fine for Pamela Geller to come speak. Funny how that works, isn't it?
I'm not going to do that though, because that's stupid. I'm friends with Jews and I'm friends with Muslim, hell even some religious. "Secular Jews" are really cool people, but the religious ones are just as fanatical or more than religious Muslims.
