The point, for me, that Fatah is making is that until non-muslims and muslims recognise and accept that there are attitudes, commands even, written down in the Koran, which espouse jihadist behaviour, and until we all say that this is not acceptable, even though it is seen as a holy book, we are simply hiding our heads in the sand.
Obviously, moderate muslims do not follow jihadist ideas, just as christian crusaders no longer go and kill in the name of their religion, unless they are nutters like Breivik. However, I rather think he's just an out and out racist rather than a religious crusader.
That's not the point. And no-one is saying that the guys at Woolwich 'represent' Islam. But they are following an extreme Islamic idea. Moderate (normal) muslims need to talk a bit louder about rejecting such ideas and not say, as the Muslim Council of Britain said, that this has "nothing to do" with Islam. As Fatah, says, it does have something to do with Islam, and we need to oppose islamic jihadism.
