it didn't mention immigration as a reason to vote for Brexit.
Because your question was so blatantly geared at that question, and one would have had to be very dumb not to have seen the fact. If you had asked "Is xenophobia one of the factors"? I would have said yes - because both of the two classes I refer to can't relate to anybody who isn't part of his clique. But I repeat, the overriding factor for the referendum result was the stupidity of the government in asking such a ridiculously opaque question of "Do you wish to retain European Union membership" and asking it of an unintelligent electorate, who wanted to embarrass Cameron, the worst PM in living memory, bar the next one........Those voters wouldn't even know what sovereignty means, or in what ways the European Union is supposedly taking over decision making powers from elected governments.
We still have our sausage. We still have our own laws. If the country doesn't like European law, they can always legislate against it.
In the meantime, a lot of European wide initiatives make clear good sense in my view - shared by the majority of the British people - if put to the vote. Which of course - would only go one way, now that those ignoramuses have finally seen the maths put up on the blackboard, and have written it into their copybook, and checked the formula on Google.
QED.
