Tayyaba;
I think you are dreaming. Without serious in-migration of foreign muslims, the demographics aren't going to change significantly in England. True, there will be a limited number of conversions of disaffected young people but inevitably, some 2nd and 3rd generation muslims will drift toward a non-observant lifestyle.
You can see in France what happens when the locals start to get nervous...they vote for guys like Le Pen.
Look at Lebanon, for eg., to see what happens when Western influences meet up with Islam...some middle ground on social behavior becomes the norm.
Now..if, as a result of cultural homgenation between English and Muslim customs is seen in England, and some middle eastern dishes replace kidney pie in English cuisine, then something good will come of it.
As it stands now, I think English muslims should be thankful they have the privledge to live in one of the most hospitable and forgiving countries in the world and stop with the foolish bravado about sharia law in England.
Attn. MI5: I voted for Bush. Please delete me from your surveilance list. Yeah team
