The second part is true but the language issue in Brussels is there for good reason, it's really a Flemish city that was lost https://en.wikipedia.org/wiki/Francization_of_Brussels
Perhaps antp's surname is a reminder of that? Not sure. (I actually haven't heard it elsewhere.)

More important right now is that in Molenbeek and other towns on the Brussels edge you have descendants of mainly Moroccan guest workers from the 60s and 70s who are still not integrated for various reasons, although they have access to the social security and education system like everyone else, and who are susceptible to radicalization from abroad. Saudi Arabia sponsors radical mosques in Brussels for example.

There were many other groups of immigrants in Belgium, Turkish, Italian, Chinese, who have all integrated, but the Moroccan community for some reason does not, as is also the case in The Netherlands. That's also a country where a public debate is possible, since Theo van Gogh's murder in particular and thanks to people like Ayaan Hirsi Ali, but not all European countries are at that stage yet.
