I read Paul's post and I see some recurring things that I do not agree with.
Independence of the regions will cause even more fragmentation. Paul seems to suggest that if Flanders and Wallonia would actually divorce, that it opens the door for provinces to do the same on the same grounds. But the same grounds do not exist today.
The language barrier does not exist in Flanders. Sure some dialects sound different, but at least we can communicate with the majority of the people within Flanders on equal grounds. If you watch RTBF or read Le Soir (which almost nobody does in Flanders) you will see that everything is colored differently. You don't see that in the regional newspapers or media.
