I think they do it...this whole radical Islamic fundamentalist, baby-killing, plane-crashing, bomb-throwing, murdering, butchering, terrorist program...simply to make the world a better place. Right?
Seriously...I think that these people are so completely incapable of independent thought, so craven and scared to face a world where they must carry personal responsibility, so completely powerless to cope with differing opinions and points of view, that every thing about us represents threat.
Think about it...to them, God is the only reason to be alive, God is the only source of thought, only religious piety has any value, the individual is meaningless, and only a priest has the capacity to make a decision.
We represent the polar opposite...Western culture values the freedom of the individual, to some extent espouses the idea of a personal relationship with one's God(s) (not to mention the freedom to choose one's religion), we value diversity and difference, we struggle and debate and argue over ideas and thoughts and social values. We are everything demonic to their way of thinking, because we think that the individual has value and generally refute the idea that we can kill anyone in God's name and it's all good.
They don't fear the physical threat we represent...they're all too happy to get dead quick. They fear the very idea that a culture of freedom of thought might upset the whole social structure they've built to avoid having to think for themselves.
The whole Islamic fundamentalist movement has made it's agenda plain and simple;
Convert and Submit...or Die.
