Good luck. EU has been producing one Europe crippling law and regulation after another and it still enjoys wide support for some reason. Ursula is facing two more no confidence votes in October so hopefully the tide is changing.
People were told the lie that without the EU there will be war again. Like the economic stagnation and decline of Europe is somehow the final solution and the end of history.
You don't have to convince me. You have to convince people who will immediately reject anything negative about EU, even here on HN (see the coming downvotes).
EU is not enough. I'm sometimes not happy with the decision taken by governments in France, so what really has to happen is HauteGaronnExit, where my departement is freed from the influence of borders decided in a Revolution two centuries ago, of which I was never explicitly asked to approve.
And, come to think of it, I don't like all the decisions taken by the departement either. Surely things will work great when my street is responsible for the electrical grid, immigration or international commerce.
And when I say "my street", I obviously mean "my half of the street". I'm not against odd-numbered houses "per se", but, you know...
