Seems to me, if you want to have rights respected, you need to respect those rights yourself and not abuse them. What purpose is served by spreading further "cartoons" that are offensive to a large population of the world. The reaction of the few who chose to murder innocent people in retaliation of this exercise of expression can only be justified if such wanton disrespect is copied and expanded. One could argue that in the context of an article or expression of an idea, the use of humour in this form helps to make the point. That doesn't extend, however, to compounding the insult for no purpose other than to offend and punish.
