Fascinating Comment on the Facebook page:
Please draw Muhammad. If not openly, then somewhere in private (and be prepared to bring him out when the time is ripe). I'm a Muslim, but the stupid death threats that non-muslim artists and teachers are getting are unacceptable, and must be stamped out by sheer numbers. I can't think of a reference except a beard.
Mind you, I'm naïve enough to hope that in answer to my request, people will actually try to draw a male human being, rather than something offensive. But extremism begets only itself. People wouldn't be pushed to make images that were offensive (to any decent person) if there weren't such extremism on the part of fundamentalists. Cultures are being polarized apart, and as a human being, I hate that. OK, rant over.
