Nonsense or fact?

So what is it?
What do you think?
And why are opinions so divided?

Granted, it’s not easy. In the Dansaert area you hear more Dutch than other languages. But Flemish commuters are often only addressed in French when they’re in Brussels. As a result, some of them even speak French to cashiers who can speak Dutch. Not many people in Flanders know that a lot of Brussels residents speak Dutch. And Brussels residents who speak Dutch often find no one to speak Dutch with.

How come? Time to debate the issue!
