Honest question: who does it harm? These aspects that you mention may not be to your (or to my) taste, but if they are relatively harmless and the other stuff is overwhelmingly good, why not let it go?
Fundamentally, the ritualistic behavior harms belief in science. Doing things because we believe in magic of any kind is fostering belief in other magic - for example healing by similar magic, the roots for both go back to Rudolf Steiner.
