"In my personal experience, of all communities, Muslims are the among the friendliest people I ever encountered while working as a self-employed tradesman in London."

Well, after I'd moved from my Catholic school in Poplar, not a Muslim face in sight of course, I spent six years at a real rough-house of a senior high school in Walthamstow. Tough times, Thatcher in the ascendancy. The school population was about 40% Muslim (I don't actually believe that there's any such thing as a "Muslim pupil", so I use the term for convenience only). The pupils were the hardest working and the best motivated of any I taught in my career. Their parents were far and away the most likely to show up at parents' evenings and work with us constructively in order to get the best from their children. The area was notorious for racist incidents, nonetheless there was a warmth and openness that exceeded anything I experienced from anyone else I worked with.
