A confounding finding from Gallup:
After analyzing survey data representing more than 90% of the global Muslim population, Gallup found that despite widespread anti-American sentiment, only a small minority saw the 9/11 attacks as morally justified. Even more significant, there was no correlation between level of religiosity and extremism among respondents. Among the 7% of the population that fits in the politically radicalized category -- those who saw the 9/11 attacks as completely justifiable and have an unfavorable view of the United States -- 94% said religion is an important part of their daily lives, compared with 90% among those in the moderate majority. And no significant difference exists between radicals and moderates in mosque attendance.
Not sure what to make of that. Maybe it's grist for Ron Paul. Some Pollster.com analysis here.
