Dreadful, but that is the result of what they are taught. In 1998-ish I was teaching modern History to a mainly Muslim (A-stream) class. One particularly loud-mouthed girl was provoked enough to argue when I was teaching about the concentration camps. If I recall her words correctly she said 'Miss, but we hate the Jews, they deserve all they got.' I was getting nowhere with her for the next couple of minutes, so swapped classes with someone next door who had visited Dachau that Summer. She gave them chapter and verse. When I returned, most of the class were almost vomiting, several in tears, and the girl in question said "Sorry, Miss, that shouldn't happen to anyone."
It took the passion of someone who had been there and seen the truth to bring home the reality. These children are children and learn what they are surrounded by and taught. The problem is that there isn't a 'Miss' to counter their indoctrination. We have to be prepared to kill children. Sorry, never thought I would take this attitude.
