It doesn't state what someone who is in an ethnic minority is - I've heard a few different definitions as it is. I'm guessing we're talking about anyone who isn't a white British born Christian. So what? As I've said (and as you've ignored on several occasions) that most people of an ethnic minority try and fit in with British life, apart from religiously. Then again, most Brits aren't bothered about religion any more. There are lots of African immigrants who are Christians and are church goers, often more regularly than British people. One of the Church of England's leading Archbishops (until recently) was African.
There is no conclusive evidence to show that Brirish people will be extinct. Extrapolating data, as Coleman has done, over such a long time frame is very unusual and very unreliable. I wonder why he chose 2066 when he could have chosen any year? 1966 World Cup. 1066 Battle of Hastings. All designed to stir national passion. If I found an immigration report denouncing Coleman's as bollocks from a pro-immigration professor, you'd be attacking it from every angle and don't deny that you wouldn't.
Simple question for you. Yes or no. Do you believe Britain should primarily be only for white, British people?
