This hasn't got anything to do with political correctness. Like in any other part of the world, borders have been set at a certain moment in the past. Arbitrarly as they may seem (look for example at those straight lines in Africa), they are there to stay. And no country in the world is happy to give away a piece of its territory. The principle of territoriality is very important for any society, so also for Flanders.This is one issue were no compromise is possible and that's why this symbolic action was so provocative. Besides, Wallonia asking for a territorial link between Brussels and Wallonia is another proof of the importance of territoriality.I don't think something that silly will happen, but then again, this is Belgium we're talking about
I just think that Brussels should be expanded to include these small communities aswell. There's no point in pretending they are flemish communities while everyone is speaking french, just because of political correctness.
I'm all for a solution that gives, for example, the four communities with "faciliteiten" to Brussels, in exchange for setting the border between the regions clear once and for all.
