No one has the right not to be offended. This hard lesson must yet be learned it seems by the Media Diversity Institute, as reported by Breitbart, who want, amongst other things, a ban on Mohammed cartoons. For illustration, I suppose the sort of thing below as published by Charlie Hebdo is what they mean.
I can't be bothered to read their rubbish. I know exactly what it will say; that some Muslims are frustrated and we should accept their murderous head chopping as the price of a diverse society. We've been here before. Evelyn Waugh featured a kind prison vicar called Prendegast in a novel, who arranged for a psychopathic carpenter convict to be given the use of a set of tools to aid his rehabilitation. He used the saw to detach the chaplain's head from his body.
But since we can't reasonably expect this sort of Darwinian weeding-out to rid us effectively of all these well-meaning but gullible fools, we must all work to uphold free speech and democracy. And that includes publishing cartoons of Mohammed.
