So many twists and turns Mair.
"... surveys regularly show that people consider immigration too high and want borders controlled , as does the Brexit vote."
Perhaps we could have some links to these surveys - how many 'people', what percentage, etc., etc. As for the referendum I keep being told that so many who voted 'leave' did not do so because of immigration but because of sovereignty, wanting the return of lost industries, etc. You seem to a special access into the reasoning behind the vote.
"We cannot be certain but I am pretty confident properly applied controls would!"
Well that's nice for you but it is not what I have heard from any party so far. They all seem to feel the need for immigration and the monitoring of boarders, which could have happened while we were in the EU, seems like a pat on the head in the direction of those who hold your sort of view as far as I can see.
"Your views are certainly not what you could call middle of the road.
Was that a typo GG or logical confusion again?"
No idea what you are talking about on this one.
"I would call my views moderate and I would call yours extreme."
How clever you are Mair. Here I am challenging your views and your logic while not putting forward my own and yet you know what they are.
