Hilarious. The above title & body text should be crosslinked in the "comedy" section. An excellent way of making your point, though.

Egyptian Coptic Bishop Warns Europe About The Dangers Of Islam

I think the problem is that Breivik is still classed as a lone gunman rather than a terrorist since he doesn't seem to have any co-conspirators. It's easy to dismiss a lone gunman's reasoning as irrelevant since its probable that they're insane. Having said that his public persona of an "ordinary polite descent sort" does fit with the profile of the 7/7 bombers.

Also don't rule out Boris Johnson trying to play this down for the greater good. Turning Breivik into some kind of anti-immigration Martyr could inspire a terrorist campaign targeting Muslims and politicians that plays right into his hands. Fortunately Breivik has somewhat prevented that by targeting children but it's still better to play up the sad loner angle driven by personal jealousy rather than suggest he was inspired by a "noble" cause.

Democracy Now! did an interview this morning with Jeff Sharlet who has written about right wing extremism in the US. He talked about Breivik's political ideology as well as the rise of extremism. Here's the link:

The usual response from right wing commentators when someone commits an atrocity based on right wing ideology is denial. So the reason they are silent is that Breivik based his acts on their ideology.

No-one should be surprised when whipping up the politics of hatred leads to violent acts, regardless of whether the origin is right-wing or left-wing politics, or religious fundamentalism.

Maybe they're just scratching around for a justification of this atrocity, because there is nothing more right than their right wing views and they couldn't possibly be wrong....could they?

All religions, but particularly Islam can be used for political or other means to an end.
There are many millions of Muslims living in poor countries where there is little or no education. It is therefore so easy to present an adulterated version of the Koran to suit those intent on wrongdoing.
The pastor in the Southern states who proclaimed he was going to burn the Koran is another example of attracting a ridiculous amount of publicity by using religion for his own ends. There are many other strange offshoots of Christianity that have sprung up in the mid-west of the US.
Boris is in no position to judge what was going on inside the head of Brievik. What we can say is that he was likely to have been weaned from an early age into right wing fundamentalist thinking, or there is some sort of mental health problem or of course he could have had psychopathic tendencies. He may even have had elements of all three. A truly shocking tragedy and waste of young people's lives.
Where did this man's hatred of Islam originate from? This is the primary question to be answered.
