Just because the rioting ones are featured on the news, that does not mean that they are the only ones with an opinion. Seems to me the plan is just to keep on insulting them until they snap and then point and say 'Look! Told you they were crazy!".
If someone spent enough time taunting you and your beliefs, you would eventually snap at them, does that make you a psychopath too? As I've said before, the reaction to the original Mohammed cartoons was somewhat silly, but the decision to keep poking the Muslims by deliberately publishing more was just plain trolling.
The low levels of education in these countries means that most of these people do not understand the world from a greater perspective, and, to be blunt, any hope of introducing better education and a more 'Western' attitude towards peoples' rights have been killed stone dead by these publications, they've seen nothing but the very worst of Freedom of Speech for years, and people seem to actually be proud of that fact.
So if you want to help that part of the world improve Human Rights, Education and Freedom then don't expect anything for at least a decade, we've shot ourselves in the foot, and whilst these countries remain as they are, they remain a threat to others. Rather than encouraging these countries towards a more 'Free' attitude, we've done nothing but put them off it for years.
