This is an ironically anti-intellectual way to engage with it. Magic isnt real, but knowledge on the natural world and medicine has been maintained through cultural practices like "witchcraft" in the past. Even beyond that, there's knowledge gained for young women in a patriarchal society when they develop relationships with other women and identify with a group that is explicitly counter-cultural on the basis of women empowerment.
Knowledge isn't just facts, it's skills and introspection. Belief in something "bullshit" is often necessary to learn something that is not "bullshit." We teach kids scientifically inaccurate information when they are young because they dont have a basis of knowledge that would enable more nuanced and accurate understandings. They "believe" in something like three states of matter and two genders/sexes because we judge that as a necessary belief to foster the skills that will enable them to learn the reality of these things later.
If they gained self - understanding and empowerment through this phase, then it isn't bullshit. You should challenge this doomerism.
