What kind of school is that and what is the ethnic background of the pupils there?
We have that in Germany as well - at schools with huge proportions of children from Arab and Turkish migrant famlies. And as I was able to see myself, in those countries Hitler is extremely popular. I got often congratulated when they learned I was a German, and was told that I should be proud of belonging to a people that had such a great leader killing so many Jews.
No joke or exaggeration, I mean it bloody serious.
