I assumed this meant high school or earlier (18 and under). Most kids I grew up with (including myself) wouldn't be mature enough to do this without explicit instruction (and some policing!). That is why I want to understand more. Example: Did they have a big school meeting where they explained to local kids: "There are bunch of war refugees coming. Here are some things we can do to make them feel more welcome. First: Don't criticize their accent when they are speaking Flemish/Dutch." It is also interesting from the lens of Belgian linguistic culture, as the country is broadly divided north is Flemish, south is French and a tiny part is German.

So "not being a dick" really does need an explanatory framework in your world (and an elaborate one, with mostly irrelevant detail). That's.......a shame.
