In reply to wintertree:
If you'll forgive me, some of those analogies are contradictory. But I should really have drawn a distinction between the issues we see in this country and the issues we see on a global stage.
We're all wittering here, like the dyed-in-the-wool western liberals that we are: none of what we say and do does a damn thing, except pass the time; we have so many first world problems that we prevaricate against tackling them by taking pot shots at people on the net who we see as different to ourselves - but who, to outsiders, are pretty much identical to us. We split hairs, thinking that they're whole elephants that we're knowingly acknowledging in the room.
Islam is a multi-faceted religion in the same way that Christianity and all of its off-shoots, splinters and affiliations is a family of individuals who fail to get on much of the time, including the cousins nobody even knew existed and the uncles in prison. To you and I, cancer is a good analogy, but only perhaps in a strict medical analogy, given the understandable opprobrium should that be advanced publicly. I understand that what a bunch of British imams say isn't going to influence radicals in Afghanistan, other than to incur their wrath; but it can influence young British men and women, Muslim and non-Muslim. Drawing clear lines on these issues - 'we don't like you satirising our prophet and it causes us unimaginable offence, but we understand your right to do so. Just, be prepared for us to respond in kind'.
It's the 'in kind' - the nature of the response from the Muslim faith - that is the crux. We keep being led to believe that Islam is about tolerance and peace - and I think that all of the Muslims we know personally embody that - but I think we see very little response to challenges to Islam which is both robust and couched in the language of tolerance. Perhaps it's out there - certainly, there are many blogs and websites which individually denounce violence in the name of Allah - but it's not given priority by the media. The current events might be a springboard for that to happen.
On the other hand, if we're looking at issues globally, then the west has done some pretty horrific things to innocent Muslims. We call it collateral damage. I'm not even remotely equipped to pronounce on the cycles of violence which ensue from that and its perhaps another circular debate to be avoided on this thread.
Sorry for the long-windedness - one of *those* rainbow bridge days at work
