Theodore Dalrymple writes in The Los Angeles Times:
Mistrust of Muslims in Britain has developed quite quickly and could develop much further. In my youth, I traveled extensively in the Muslim world and lived for a time in Africa with a Muslim family without being aware of any hostility or antagonism on my part toward the religion or culture (had I been a woman, it might have been different, of course). Contrary to what the late Edward Said, author of the anti-Western "Orientalism," might have thought, I had inherited no anti-Muslim prejudice.
Now, despite friendly and long-lasting relations with many Muslims, my first reaction on seeing Muslims in the street is mistrust; my prejudice, far from having been inherited or inculcated early in life, developed late in response to events.
The fundamental problem is this: There is an asymmetry between the good that many moderate Muslims can do for Britain and the harm that a few fanatics can do to it. The 1-in-1,000 chance that a man is a murderous fanatic is more important to me than the 999-in-1,000 chance that he is not a murderous fanatic: If, that is, he is not especially valuable or indispensable to me in some way.
