I'm delighted to cite some of the Fuad Nahdi interview (if the same point had been made by a critic of Islam it would be shouted down by the bien pensants (Standup - you know who you are!) as paranoia, bigotry, Islamophobia, or whatever):
"Q: How did this extremist thinking become so prevalent in a faith and culture that tends not to be extremist?
A: It's not something that happened overnight. It has taken decades to develop. According to intelligence reports during the last 30 years, investment has been put into this extremist ideology. We are talking estimates of over US$15 billion. To the best of our knowledge, there is no ideology in the history of mankind that had such massive resources put into it on a global level.
...
The crux of the matter is the theology. Islam is a belief system. It's a series of mistakes, one after another -- of bad analyses, reactionary negative responses and just total misunderstanding. To counter, we're trying to sustain and nurture a mainstream form of Islam that has been lost for decades now. We want to define Islam, not by the terms given it by the extremist and the radical elements".
