Brexit may be too late. One of the tenets of the EU is free and open travel within all EU countries. And so many EU countries have been welcoming Muslims, radical and moderate. for years. I don’t think Britain can yet stop the influx. And from what I read recently, London is no longer majority ‘White’ British. Under 50% identify as ‘White’ British in London. I hope the English can regain control in London. I so love it there and it is heartbreaking to see it go down this road.
