Well we are the EU and so far we have agreed with almost every new law, rule and regulation, demurring at very few and modifying very many via our constructive input.
No, we are not the EU (unless you are speaking from your viewpoint as a staunch pro-European, and even then saying "we" is far too inclusive). We are currently a part of it.
We have gone along with many of the new laws, not because we agree with them, but because we were (or knew we would be) outvoted.
A little pragmatism goes a long way, but there comes the point when the people of the UK (or at least the majority of those prepared to vote) decided we did not have sufficient clout to avoid being dragged into a "United Europe" so we are getting out.
