The United Nations are afraid that the Flemish "Wooncode" may lead to racial discrimination: speaking or agreeing to learn Flemish has become a condition to access social housing in Flanders. I think it's the other way around, that it really promotes integration, but that's not the problem. The problem is that language is being used as a weapon against French-speaking Belgians, keeping them on their side of the fence in the area around Brussels. And this is the worst way you can use your mother-tongue. It becomes a vehicle of hate.
