Also worth considering is that it is part of a broader ideology of Anthroposophy which sometimes aproaches semi cult status in how people identify with it. A lot of the principles of Steiner schools are actually pretty cool, but sending your kid there, depending on the school they will also be dealing with the more esoteric bits of all of this that have very little to do with didactic or pedagogic sound principles.
Some if it includes some schools teaching some of the more racists views of Mr Steiner.
This is probably true of every school that follows a philosophy or belief system.
It needs addressing. The school was white wealthy hippies when I was there. It’s vastly more representative now.
