As far as Joey Ray's argument that we don't hear of Muslim condemnations because that type of news doesn't sell, I don't quite buy it. After each attack inevitably all the newspapers and talk shows are publicly asking "Where is the Muslim condemnation? C'mon Muslims, step up and make your disapproval public!"
It seems to me Muslim views are sought out, not ignored. And it makes sense; westerners want the violence stopped and making Muslim condemnation against these types of attacks public would be one valuable tool in the quest to influence Muslims to reject violence.
Actually, he is somewhat correct on this point. Speaking as someone who has actually tried to get letters and articles published on the matter, I can assure you that the media would rather devote space to the semi-literate rantings of extremists than give a platform to Muslims with a serious anti-terror message.
People like Kamal Nawash do get booked now and again (eg. he has appeared on Fox News a number of times), but on the whole they do not. Following the recent terror busts in the UK, for example, Sky News decided to do a special interview with some associate of the infamous cleric colourfully known as Captain Hook. This guy wasn't some high profile Muslim leader. His 'claim to fame' was simply that he was a friend of that cleric. Yet they allowed him to go on the air for a significant chunk of time and rant like a lunatic. Meanwhile people like Kamal (whom I use as a specific example because I have a personal association with him and his organisation) do not receive the same kind of attention.
Even Mark Steyn, hardly a fan of Islam and Muslims, condemned the media for how little attention they gave to the anti-terror protests which followed the bombings in Jordan, and complained that if the protests were anti-Bush in nature the media would have plastered it all over the place.
Furthermore, the most powerful Muslim organisations in the west are the Saudi-funded ones (eg. CAIR). They gain a position of strength thanks to the oil-money which gets thrown at them from their Saudi backers, and therefore when the media does decide to put on a 'moderate' Muslim voice they use people like them - even though they are pretty much extremists in moderate clothing.
So, have no illusions - the deck is very much stacked against people like me and the organisations we support when it comes to getting media time. Hopefully when my book comes out next year I can grab a little more attention if it does tolerably well, but that remains to be seen.
With that said, there is no question that many Muslims demonstrate an infuriating silence over extremism and terrorism yet will rant and rave like a mob of degenerate idiots over trivial things such as a Papal speech or some cartoons in a paper. In part this is due to their leaders (both religious and political). It's no coincidence that these demonstrations tend to happen after Friday prayers, when imams have had a chance to whip people up into a frenzy in the hope of enhancing their own status by creating and demonising an enemy. Or to further their own ideological agendas by doing so. There is also an element of primitive tribal mentality. In much the same way that lots of black leaders will speak out vehemently about incidents (real or supposed) of racism against their group but will bend over backwards to ignore or excuse black crime, a lot of Muslims have a tendency to demonstrate a great apathy to Islamist violence but react with Heraclean fury towards attacks on Islam.
