The Exorcist is not allowed to be shown in the state of Victoria on Good Friday! (Makes crazy indignant huffing noises) And why? Because it's too offensive to Christians! I'll give 10 cents to anyone who can name six people they know to be practicing Christians!!
So who does Bracksy think is gonna be offended? Because if he thinks they're going to be offended by the Exorcist, won't they possibly be offended by Almost Famous (worshipping false idols), Amores Perros (swearing - the title means Love's a bitch), Dude, where's my car (stupidity - ok, that doesn't break any commandments, but you know it should!) and Quills (I'm sure the Christians have something to say!)
And what about people from other cultural backgrounds? Aboriginals don't appreciate seeing images of aboriginals who are now dead, in Chinese culture, the number 4 is deeply inauspicious - it was for the Lethal Weapon series, too, heheh - and Muslims aren't too keen on images of humans at all. And I'm not even going to talk about offending all those Satanists....
