I lived outside of London (High Wycombe) for 5 years when I was a young teen. About 80% of our neighbours living on our block were muslim. My two best friends were both pakistani immigrants, they were probably the best friends I ever had.
That said, there was a family who got deported 1 block from my street because one of their sons was involved in the 7/7 London bombings. Pretty creepy stuff.
I also heard a pollthat stays with me to this day, 30% of all muslims living in the UK think that 9/11 was a good thing. 10% said they would activley participate in a terror attack againt the west if given the opportunity. 2% of all muslims in the UK are active members of a terrorist organization.
