Hi Le chat,
I think you have raised a good question,but in defence of Islam,it is a very peaceful religion,I know you wouldn't think so at the moment, but only the top clerics are going to be able to sort out the fanatics,the scary bit is that a lot of these lunatics are British born,but they have been brain washed into thinking that to kill is ok, a complete contradiction to the Koran, It is also a bit worrying that some of the people that are running the country won't say anything because it might offend, it is a joke, I hope we can live together peacefully,but as you rightly say if they don't like it here,they should go live somewhere else,
Lets hope sense prevails,but don't hold your breath,will you,
