On the other hand, I wonder about Flemish, generally, toward Wallons, if that's not hatred that could be a big hint of that...
It isn't. In general what we have going on round here are just some 'ordinary' political problems which are not driven by racial tensions. If there is electoral gain to be found in nationalism, that finds its origin in the media and mainstream parties blaming the 'unworkable' structure of the
Belgian state. Racial hatred plays no role whatsoever in the Flemish Mainstream.
Hungarians hating the Roma is very much a fact. And unless my memory is way off, they aren't particulary well liked in Romania either.
