I don't care what anyone believes. Most of those beliefs I take as seriously as a grown adult believing in the tooth fairy. Just do not impost it on me, change my society or others like it because of them, hack someone to pieces because of them etc. At least act like a civilized person. Do they really think this or other acts like it will stop the western world's OVER involvement in Israel and the middle east. I wish they would just get out of there and let what happens there, happen. Also some immigrant groups have a more difficult time adapting then others do. That is just common sense. Think of us. Where would we adapt faster/easier Canada, Denmark, Germany , or Cambodia , Somalia or China.
With regards to Muslims in Europe there are plenty for generations in the Balkans
