Most people would think it did, but I say it did NOT. It was the "religious fanatic faction", the 2%ers, that created 9/11. The ones that take the Koran, the Bible and use its words to promote THEIR VERSION of a religion. They work in their religion's name, but its no different then the Son of Sam or other notorious killers. They have a thirst to kill, period.
Religions, including Muslim, possesses practitioners that are mostly peaceful, loving family people. The large majority of EVERY religion has rebuked the senseless killings of 9/11 and surrounding events.
So I say it is unfair to blame ANY religion, or religion itself for the acts of a few percent of the bad seeds. We wont truly win this war until we can make that distinction.
