heninthemidden,
I feel I need to apologise that people like TheRationalist, barking, and Northernrefugee39 have hijacked this thread for their extremist ideological secular humanist crusade against Steiner schools, making the discussion as mental as they have, much unfoundedly trying to smear and defame Steiner schools as much as they possibly can for primarily ideological purposes, keeping most normal mumsnetters (like nevergoogledragonbutter and others) from participating in it.
Maimuna, I'm sorry for what happened to your daughter at the Steiner school. At first I felt sceptical about what you wrote about what the teacher allegedly read from a "Steiner poem", a scepticism that turned out to be justified when I tried to check up on the verse you referred to.
While the verse as such possibly comes from another more racist time than the present (the author was born in 1925, and the book may have been printed for the first time in 1993) the teacher's choice of verse was thoughtless and she then made it even more racist by translating "Neger" (in German) as "nigger" and then in addition not even realising and understanding that this is a clearly offensive racist word. This was and is indefensible.
As I've mentioned, research (in Germany) indicates that her attitude probably is far less common at Steiner schools than at other schools, if judged by the attitudes of Steiner pupils.
I trust that the school has or will take the proper action with regard to the teacher, and that the Steiner Waldorf Schools Fellowship takes corresponding actions to prevent any similar incidences from occurring at that or any other Steiner Schools in the UK and Ireland in the future.
They are indefensible whereever they occur in society. I'm sorry your daughter and you had to experience it, especially at a Steiner school.
