I'm 50/50 here
Obviously I condemn the attacks, and any form of violence. I also believe in freedom of speech as a basic human right but try to reconcile that with using it responsibly and avoiding causing offence where I can. Not because I have to, but because I want to.
In the wake of the attacks I totally support CH publishing the image it did. Even if they had decided they didn't want to because they thought of something better, they had to. It's a statement about not being censored by a minority of crazy people (terrorists, not Muslims).
However, I'm also in support of other media outlets deciding not to replicate the image. Not because they were scared of repurcussions (which let's face it is most of them if not all), but because while it's important to stand up to the extreme and violent it's also worth keeping in mind the huge numbers of non-violent Muslims who find the publication of this image incredibly offensive.
The world would be a much happier place if we could all stop doing things we know will upset somebody unless there's a good reason to do it. And more importantly if we could respond to the things which upset us by calmly explaining the reasons why it caused offense and discussing the possible alternatives for the future.
