As an EU citizen you could try to change the institution.
Are you one of these scumbags paid by the European Parliament to troll on forums? Of course one can try though with the current system, it's doomed to failure.
BTW: France is part of the EU as much as Germany or the Netherlands, therefore it is only fair to summarize all these countries with the EU flag, just like US states are all summarized by the US flag. Yes we are not that one country as the US is, but it is very close.
This is not the united states of Europe. Nobody wants that in Europe (I mean, as in, the people doesn't want this, at least anymore). There's more and more sovereign movements raising, and they will get even stronger as time passes. So, it has never been, and never will be fair to replace the flags of individual countries (did you notice I didn't use the word state?) by the European flag.
