"Sorry Jim, but that's completely wrong."
We..eeel !!!
Think I ma have put it badly

No argument with what you say about the reason for them in charge to leave Europe - of course it is as you say - all moves such as this are motivated by such reasons.
I'm referring to why the idea was taken up by a significant enough minority of the population to be passed
It was sold and bought on a racist ticket - a classic case of divide and rule

Whether rabid ranters such as the one strutting his stuff on the other thread like it or not, Britain is now a solidly multi-racial and multi-cultural society - in essence, it always has been - Britain could never have become as wealthy and powerful as it did without having to ponce off other nations and cultures - "The Empire on which the sun never sets, they called it ("and the blood never dries", they usually forgot to add)
The incoming of the ex colonials after the fall of the Empires was inevitable - it provided the great and good with a perfect scapegoat to maintain power - while we were fighting each other we were ignoring what they were doing

Things like Brexit never have a singe purpose
