Why should we be ashamed of the result of a democratic vote?
Why should we approve this so-called Constitution?
Maybe some of us voted "Non" for some wrong reasons (not related to the treaty itself), but my feeling is that this "Non" is a chance for us to question the way the european construction has been done so far.
Let us take this opportunity to ask ourselves what Europe we want.
I personally think Europe should be built by and for its citizens. A democratic Europe, where the people (or their direct representatives) would have the final word to decide on the path to follow.
The treaty that was presented to us didn't go that way and was rejected.
I don't call this a shame, I call it an opportunity...
Some have started to build upon it to start a work on a real Constitution by creating a Constituent Assembly.
