If it's not a three way civil war or a government tolerated (if not sponsored) murderous horseman militia, then it has to be reactionary extremists longing to murder anyone even perceived as threatening their deep deep religious insecurities. I know some more traditional groups from the Sudan were quoted as saying "This was an innocent mistake" and other younger Sudanese groups stated "this is ridiculous and she should be released immediately".
Still, there is that "stuck in the dark ages of ignorance" class of society who want the very life of a British woman who allowed her 7 year old students to name a stuffed bear Mohammed. The name finally gets its "Teddy Roosevelt" moment and this is perceived as anything other than adoring familiarity!? There are many regular old good and bad men who share this name, because it is promoted with murderous rage throughout the society. A little research can help one determine for one's self whether "murderous rage" is an appropriate description of the activites of the Janjaweed militia in Darfur, Sudan.
One great mark of the success of this rhetoric should be that a group of children in this Islamic society want to associate something adorable with a prophet whose name they adore!
When some choose to make death threats against a school teacher over this, It is the depth and height of ignorance. What should be punishable by lashing and death is to threaten an innocent school teacher and honorable woman with death and lashing over such a non-incident.
Instead, sprained and broken reasoning is used by fanatical adherents whose devotion and hypersensitivity has rotted their common sense.
It is a wholly inappropriate and intolerant response to an innocent choice which actually exhibits deference to the very leader whose name and teachings are said, incredibly, to be insulted. It is truly difficult to decide who exhibited the most childish behavior in this situation.
