Why don't they riot about this?
We should never apologise to clerical fascists, it's none of their damn business what we print, read or write. They are the last people who would ever deserve any respect (see above). If you are not a follower of a religion, the rules of that religion do not apply to you. If they try to force them on you, just say no.
Are we to have a silhouette instead of a picture in a sequence depicting Arab rulers? Here is Caliph A, in typical costume, here is a blank space because we can't show you what we think this guy looked like, and here is Caliph C in his grandeur. It's preposterous.
