You must know quite a significant number then, but quite possibly none from Luton, Burnley, Blackburn, Rotherham, Rochdale, Bolton etc where many of today's radicals seems to be recruited from. These seem to be populations that really do not wish to integrate and I have had first hand experience of this from travelling the length and breadth of the country to follow NCFC. Sure there are those that do integrate and I met several in my sheltered life in sleepy Norfolk and Cambridgeshire but that is not the same "reality" of the large northern towns and cities, from what I have observed.
I accept that because they do not wish to integrate does make them "Islamist's" by default but those who do not wish to have contact with the indigenous population have not, and are not doing themselves any favours with a self-imposed barrier to anything outside of
their culture/religion.
(Not sure how that could be antagonistic in the slightest)
I left just over 5 years ago with no regrets
