Has anyone heard of this controversy? In Islam, it is forbidden to create a depiction of Muhammad because it may lead to idol worship.
http://en.wikipedia.org/wiki/Jyllands-Posten_Muhammad_cartoonsWhy would they be offended if non-Muslims depicted Muhammad? In Judaism, the word God is written because it is considered disrespectful, but (as far as I can tell) they don't object to other people from writing the word God. BTW, you will see Jewish texts use G-d.
