Similar thanks for responding in an even-handed way.
I wouldn't call it a shot in the dark, there is undoubtedly some element of risk but then a huge, unprecedented constitutional change will fairly naturally carry this.
Yes I do want a better policy on immigration. It is ludicrous to have a system of unfettered access to a select group of nations, it inevitably leads to passing up some of the world's best talent. Leaving aside all the other stuff, do you not accept something akin to the Aussie system would be fairer overall and better for the UK?
I could well be wrong about the economy. This whole debate is predicated on unprecedented events but the evidence suggests to me that ultimately the economy has enough about it to prosper. Short term pain will almost certainly result as our financial system works on confidence and uncertainty destroys this. However, if you accept (as I do) that it will ultimately give greater scope to trade with the wider world then unfortunately this has to be accepted as a consequence. There was no way a Brexit vote would ever occur without that sort of shock, but Mark Carney (a remainer of course) has already indicated that the strength exists to cope with this. How long for it to settle? Well, if I knew for certain I'd probably be a very rich man but my guess is that negotiations on exit will be concluded ad rapidly as possible to lay the groundwork for stability.
To take your example on progressive laws, let's say the EU decided to start repealing such laws? What could you do? What could you do if they passed any legislation you felt was utterly wrong? It might not happen, but it might and therefore staying in has its own risks in this sense.
UK governments are powerful and can effect change quickly but can still be voted out. This debate might not apply for the next 20 years but I simply want the electorate - and the Parliament it elects - to decide what's best.
