I think to some in Europe, it's an ideal. Given our different history, that phrase causes a lot of worries here.
That phrase has not been mentioned these last few weeks - the NO campaign is focusing on sovereignty, not about "taking back specific powers." The claim is that there are directives and laws which come down through the EU that sovereign governments have to make into law - the question Michael Gove raised in his article was if the public don't like that law, they can't vote a govt out to change it. So - think back to Poll tax - the public disliked it and had a govt / politician they could focus on to pressure into dropping it.
If something agreed at EU level and then the European Court of Justice makes sure it is implemented across europe equally - but if a group of citizens dislike that law; who do they complain to or vote to get out?
I'm giving a loose example as I know you will correct me on how EU law is made and I am also cognisant of
this "The European Union is based on the rule of law. This means that every action taken by the EU is founded on treaties that have been approved voluntarily and democratically by all EU member countries."
I'm aware of your position - what I'm asking you to see is the perceived problem of not whether the laws are democratically made / just / equal or correct - but about whether citizens of a country can complain about them and have them changed if they don't like them.
