I remember when the film 'The Last Temptation of Christ' came out, (Scorsese, 1988) there were howls of "Blasphemy!" and many Christians were outraged. However, the film seemed to me to be exploring sensitively a 'what if' idea, and I found it very interesting and moving.

Mohammed's marriage to a young girl doesn't necessarily make him a paedophile. He advocated taking vulnerable women under one's wing in marriage as a way of protecting them. A young girl like that would have had no sexual duties until she was older.

Before getting all het up about religious remarks, art, opinions etc it might be worth reflecting a bit about the context, facts and motivation of the 'perpetrator'. Unless deliberate provocation and hate-mongering is intended, it may be better to let it pass. That way, one isn't giving it an airing!
