I'm surprised some people don't realise what the EU actually is, and what it intends to become.
It is not a trading bloc. That's what we were told in 1973 (when the Tories took us in, with no mandate) and again in 1975 (Labour's referendum on staying members), but with every new 'treaty' that becomes less and less true. The EU is really an attempt to create a continent-wide superstate, something along the lines of a United States of Europe.
If you follow the direction of travel of the ECSC / EEC / EC / EU, it's plain what is going on. They are aiming for full political and economic union, and the reduction in status of current nation states to provinces.
As most of the citizens of the countries affected don't want this, it is being done by stealth and degrees with no democratic input. Don't for a moment think your MEP - who I bet you can't even name - has any political power. The EU 'Parliament' is a sham.
If we abandon Brexit now, quite apart from the humiliation of our democratic decision being overturned by a mixture of EU machinations and fifth columnists and anti-democrats at home, the price of re-admission will be to adopt the Euro, join Shengen and give up our rebate. For starters.
Read Varoufakis' book 'Adults in the room' if you really want to know what the EU is about - and it is certainly not the well-being of the peoples of Europe.
We are leaving because we don't want to end up as a gaggle of ahistoric offshore provinces of Greater Germany, ruled from Brussels by unelected, unaccountable, unsackable foreigners. If achieving that breaks a few eggs, so be it.
