I don't buy that 'not having a pop at Islam' is down to being scared - or somehow 'not being allowed'. The truth is that most people, myself included, know hardly anything about Islam. This in contrast Christianity, a religion bound up in the state, schools, architecture, media, social life etc etc for a millennia and a half or whatever, undergoing tumultuous change - not to mention considerable moderation - along the way. Like most people, I can't say anything about Islam these days. But then I don't actually know anything about it, so it's probably best if I don't. You don't have to go back too many centuries in England before such a poster would have earned you a cruel, summary death. Where and what will Islam in the UK be in four hundred years?
