Exactly How are are they being alienated? Someone give them dirty looks?
“Ever seen any Muslim panhandlers, criminal gangs or racketeers?”
Yes, and so would you if you had any real experience with Muslims. In Europe they control the drug and prostitution rackets in many cities. Muslim gangs are practically the only seriously violent criminals in most Scandinavian countries which had not had a problem with crime until large numbers of Muslims emigrated.
“If you actually knew any immigrant Muslims you'd discover this for yourself.”
I have had more experience with Muslims than you have apparently. Your ideas about them are naive in the extreme.
“Try getting some experience before throwing down blanket judgements upon others.”
You should follow your own advice.
Seems like your experiences and views are based in Europe. Maybe you should restrict your opinions there as well.
