I don’t think he understands “mockery.” If I were to draw a picture of an Arab-looking man in late middle age and call it “Mohammed,” it wouldn’t be mockery. It would just be a crummy drawing of an Arab man. If I were to attempt to draw Jesus, Moses, Buddha, or a Hindu deity ... same thing: just a lousy drawing.
It’s not “mockery” that sets off Moslems: it’s the existence of non-Moslems.
There is a difference between mock and defy (and e-s needs to get this straight too, the apostles DEFIED the pagans, there was not anything remotely coming close to an Elijah episode in their ministry).
