It's not an easy situation at all. For me it is clear somebody is obviously taking political gain out of it. Why else stir things up 6 months after the actual publications?
However, these people have the right to be offended (mind you, they do not have the right in my opinion to be voilent). In Europe we have seriously large communities of Muslims, who protested peacefully thank goodness.
In Holland the news arrived that the same Danish newspaper refused to print Christian cartoons because they might offend the Danish...like Pecker already pointed out, weird way of doing business. The thing is, that these newspapers are exploiting the freedom of speech. It is being used to merely offend, what other purpose does it serve? Simply saying that you 'have the right' to publish whatever you want doesnt cut it. You have to take into account what goals your trying to reach, and if you can think of none, but you can be damn sure people will be offended, why post them? This discussion is going on in my country, The Netherlands, and in all of Europe since we seem to be more and more the test-tube for this worlds social problems and solutions...but hell, we have been throughout history.
And then what about the ga-zillion newspapers who copied the cartoons, and even posted new ones? What goals do they serve? Think aout your fellow man folks, and think about how certain personal issues that you hold very dear, while others may not, might offend you as well when being mocked with.
