There is quite a bit of this on this thread.
There's also a lot of Hard Right Bingo phrases in this thread too...
"native born"
"waking up"
"liberal left"
Etc.
The root of the problem is an insecurity about what it is to be British in a changing world. Things are changing too quickly for some, and they see isolationism as the solution in the hope that shutting the door to the outside world will maintain the status quo.
The UK right looks to the US as a role model, it conveniently speaks the same language and there's a perceived common culture as a result. But the US is a huge nation, it's not a small island on the edge of a larger, prosperous continent. It's sheer size is a buffer against short-term impacts.

Farage admitting it's a dictatorship in that he can't be deposed or told what to do, and he's not accountable to anyone. They've no policies except "Leave means Leave" with further detail to be added once they speak to their "subscribers" (and the millions from Aaron Banks, etc. add up to a lot more than the £25 donations from "normal" people - let alone all the foreign
