How exactly is the BREXIT going to help the UK when they are quite happy to create this hell for themselves?
Not that BREXIT is a bad idea as such (less UK PC madness spreading to the continent), but 50+ years of freely importing riff-raff (Pakis, Africans, Arabs, Caribbeans) have pushed them over the point of return.
Make that, point of NO return...
After Churchill, Enoch Powell may have been the last sane UK politician of note. (What did even the great Maggie Thatcher do to stem the flow, after all?)
The PC madness flowed in the other direction for ages.
To be fair, most of the immigration to the UK has been fine. The Sikhs and Hindus have been great. Muslims were fine until the late 80s. There were racial issues and tensions with the black Caribbean community for years, but that settled down years ago. And of course you have Chinese/Asian immigration, who have been terrific.
I am no hippy trippy PC person, but overall, despite some issues and problems, the ethnic immigration to the UK has been positive. At least from the 1940s until recent times.
