Rather than placing a greater responsibility on the islamic community, I think the responsibility falls on all of us. This responsibility is to wake up, and realise that muslims may be peaceful, but islamism is not. Such a contrast in behaviour suggests motives that are outside anything socio-economic, leaving many wondering why. The fact is, is that it's a religious, I would say spiritual, force that not only binds serious adherents of this religion, but also gives each the follower the potential to become a ticking time bomb.
This won't be true for the majority, but it serves to help remove the clever mask of politeness and decency that many muslims would have us believe is charateristic of this religion, the image that the western muslims who don't closely follow the koran try so hard convince us of. In the koran we find similar ordered, civilised, and otherwise decent people who take up the sword for islam at a moment's notice. This religious heritage, coupled with a spiritual catalyst, is the receipe for otherwise unassuming folk to commit spontaneous acts of killing and destruction. Hagar heard right when God told her he would bless the descendants of ishmael, but that "his (ishmael) hand shall be against every man, and every man's hand against him. Andh he shall dwell in the presence of all his brethren."
