The publishing of the Muhammad cartoons in Denmark was the finest example of freedom of speech, and the very idea they should have been censored or suppressed is absolutely disgusting. The reality is no one would have come to the defense of Christians rioting around the world and killing people over Piss Christ.
Publishing controversial material and the freedom to do so is enshrined in the principles of democratic societies. Being willing to publish something that might make people angry, if there is a need for the material to be made public, is part of what journalists must do. But just because something can be published doesn't mean it should be. Doing something just to make a point, knowing it may unleash unrest is not advisable.
