It is not the quran that causes people to do things like this, it is people interpreting the quran in their own way and for their own purposes and then projecting these ideas on to others in order to take advantage of them. Very few people sit down and read the quran with no outside influence and think to themselves, 'wow, I should be ******* bombing people.' In fact, I doubt hardly anybody does unless they are already a piss poor person morally and want to kill people to begin with.
Just as priests have taken advantage of their influence over young and manipulatable christians in order to use the 'word of god' for their own personal gain/wishes to be carried out, there are 'muslim' people (mostly the terrorist recruiters, and people like osama) who manipulate young and naiive islamic people into carrying out their wishes of terror and destruction.
You are associating the religion of Islam with terrorism, claiming that Islam provides a particularly easy route to terrorism, like claiming that being black provides an easy route to becoming a criminal. Realistically, it has nothing to do with the fact that someone is islamic or black or christian or white, it has to do with the influential people in their lives who poison them with their own agenda; People who they percieve to be just like them, and who gain their trust and manipulate them for their own purposes.
If anything, if you actually knew what Islam is truly about, you'd understand that its founding principles are really just much stricter versions of everything Christianity is founded on.
Again, Osama bin laden is not an accurate representation of a Muslim man. Not only that, but who exactly are we fighting in Iraq? Terrorists? Really? That's like another country coming to america and sweeping the streets, killing those who get in the way, in order to fight drug dealing.
