of course it's a minority but it's vocal, it widely operativeand therefore is has some support.
For instance, check how the religious law it's implemented:
http://en.wikipedia.org/wiki/Sharia
The religion is incompatible with modern ideals and values, to make it compatible people should distance themselves from part of it, this makes the moderates.
It has happened with christianity during a long process, it should happen with Islam too, for the benefit of everyone.
Fundamentalists are scared of progress, and progress is achieved through debate and satire, this is why they hate freedom of speech.
Ignoring the religious issues won't solve the problem, this is why hundreds of european and american born young people have choosen to join a barbaric war in a country that is connected to them only by religion.
