Debates such as this just go on and on because there is no absolute right or wrong - it comes down to individuals opinions and that's what will happen with a vote. Personally I'm pro Europe simply because I don't want a return to trade protectionism and import controls where the rest of Europe would no doubt tax the 50% of our exports that go there into a competitive black hole. I'm willing to take the compromise on legislation where some of it suits us and some of it doesn't. Overall, I'll stay in Europe and expect our government to fight from within rather than outside the union.
I also believe that if you roll the camera forward 500 years the world will have a single federal govt as that's the only way the human race can survive by financing the inevitable task of locating an alternative
planet for us to live. What we're doing now is simply going down that path towards total federalism as the days of small independant governments around the world are numbered

Controversial huh? ;D ;D
