The "UK" of which you speak will -- in our lifetimes, perhaps -- cease to exist. London will be majority Muslim within 10-15 years, and 30% of England's population within 20 -- over 3 million now, TRIPLED in just the past 25 years. The noble past you describe is all factual -- and completely irrelevant, as it was not populated by Islamic savages.
No, it will not. The UK is 96% NON Muslim and that’s after 60 yrs of Muslims. The rise in Muslims will see the UK have 5 or 6% Muslims by 2050-2100. The idea that 4% in 2016 will be 50+% by 2050 or even 2016 is nonsense.
The Muslim birthrate will drop in coming decades not rise, allied to restricted immigration. The most loose estimate I have read says 10% UK by 2100, the average estimate is 5% by 2050, 6% by 2100.
The idea the UK is going to become some Muslim state with white British and non Muslims in a minority is balderdash old bean. Muslims aren’t even the largest ethnic minority in the UK in 2016!.
