I used to live in a Muslim area up North here in Bongland. some were pretty chill and I had respect for, like my barber was friendly and always had a good chat, and worked 2 jobs.
My driving instructor was a sound guy and self made man. And the local shopkeepers seemingly worked 12 hours a day 7 days a week.
Not to mention I had a coworker I was pretty good friends with.
On the flipside you have the fact that it was a poor area, loads of weed dealing going on, and you could tell most of the tennents were benefit scummers as if I had a late shift, surprise surprise the cars were all still fucking parked.
Plus one old guy used to sit on a wall by the shop at times (for some reason) and spit on the ground when my and my girlfriend walk by until I told him to fuck off.
Basically if Muslims can integrate themselves into regular society they're fine, often times admirable. But if the only thing they subscribe to is the Quran, and they're own people/culture, everything starts to devolve.
