All Waldorf schools aren’t created equal, but things I’ve seen are anti-vax beliefs, hard belief in mystical karmic stuff, a sort of groupthink that encourages conformity and obedience and shunning of people who question authority, and (and this one is really strange IMO) a prohibition on fantasy play among the children (eg you aren’t allowed to pretend you’re running a restaurant and your friends are guests —- for reasons of crackpottery).
The problem with spaces like this is that manipulative people easily take over the rudder for the whole school combined with that it attracts a certain kind of free-thinking and liberal people who get wooed in and enable it all.
Edit: there is a Swedish documentary about one of the schools my brother went to.
I’m on board with some of their rules, but no listening to prerecorded music is where they lose me.
