Ever since Belgium was created in 1830 the Walloons held the upper hand in our country because, as you may know, Wallonia was the first industrialized region of Continental Europe. Since then they have tried to impose the French language on Flanders. Dutch, or Flemish if you will, was treated as a second rate language. They were and still are hypocrites: they want to protect the French speaking people in Flanders, but they don't tolerate Dutch speaking people in Wallonia. The university of Gent was only
vernederlandst during the Interbellum. Yes, a Dutch speaking city with a French speaking University.
They also keep coming to Flanders without wanting to learn Dutch. Brussels, once a Dutch speaking city, now a Francophone stronghold. And they're slowly turning the gemeentes near Brussels into French speaking zones(the whole Brussel-Halle-Vilvoorde dilemma). They want special language rights in Flanders... I have a better proposal for Walloons who don't want to learn Dutch if they live in Flanders:
The picture is at a protest in Leuven where they wanted a Dutch speaking university instead of a Dutch-French one. So the Walloons got "kicked" out and created a new city over the language border: Louvain la Neuve.
