You mean British Muslim immigrants? I cannot remember how Canada has handled these same requests from their 'Muslim populaiton'. . .citizen or otherwise.
Western governments should know by now, what to expect from large populations of Muslims who immigrate into their countries. And they should be figuring out what to do about it.
No, I didn't mean Muslim immigrants. I meant anyone else who may be considering fleeing at the thought of a Muslim Britain. (If I lived there, and had the insane policies their government seems to have, I'd read the writing on the wall and move to the U.S.)
