My kids went to charter/public Waldorf. I personally am Catholic (not Protestant-adjacent like Waldorf tradition) and even though they do have some weird ceremonies that I am happy the charter Waldorfs don't adopt, my decidedly agnostic-to-atheist siblings sent their kids to private and charter Waldorfs and did not seem to find it so much of a problem. A Dragon Pagaent focused on Saint George and the Dragon (which we did have) is not much of a problem for most I would say. There is a chance you had a bad school. There are problems in every school, but none centered around Waldorf curriculum for any of us, and collectively we have over 50 school years of our kids in several different Waldorfs around the US. Any older pedagogy: Waldorf, Montessori, traditional schooling - they all need improvement. Still, there is no need to throw the baby out with the bathwater.
