We need to keep in mind that any expression of disbelief in Islam or Muhammad is technically an "insult" to Muslims, and that the controvery over the cartoons obscures the real issue, which is Islamic intolerance, not Western insensitivity. We are far more sensitive to their concerns than they are to ours.
There's an understatement.
I haven't noticed any effort at sensitivity on the part of Muslims for Western/Christian concerns, except mealymouthed lip service in the midst of one of their many complaints about unfair treatment...and even that ONLY when they are in the minority, such as currently in the U.S.
