K, now draw a picture of muhammed taking a load in the face, and put it on your fridge. Now walk down the street. No bullets? Didn't think so.
Now get either picture published in the wrong place, or show it to the wrong group of crazy nutjobs, and I'm pretty sure they'll try to shoot you. To make it easier for you to think of an example, think of "The South". It's not a fair characterization of the southern states of america, but there have certainly been examples.
admittedly, the "wrong place" for a picture of jesus isn't any international newspaper... but that's probably more the result of the relative socioeconomic situations of the places where christianity and islam are most widespread.
