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).
