Well, face it. None of the Nordic countries could be defined as very religious, jokes about all religions occur frequently, even though religions of those with darker skin should be presented by themselves (which also occur frequently).
Is it suitable to portrait muhammed with a bomb? Well, doe´s any of his followers use boms in such fachion that we have a reason to joke about it? My opinion is that things not worth joking about is not worth mentioning at all...
It is also clear that the freedom of speech, freedom of the press and its indisputable strong significance in a democracy is not as clear for people with no, or little, tradition of just that.
To all this you can add the extreme collective approach to something that a couple of Danish journalist are responsible for, and why are we surprised? What makes the media tick is confrontation and conflict. If you don´t have´m - make´m!
Then report of "danes" hating "muslims" and exaggerate every possible result/aspect of the original bullshit...
