Only if “what people used to believe” means “real occultic practice.”
Are you willing to assert that?
Her use of the phrase “what people used to believe” is disingenuous. She, more that likely, knows full well that people still believe and practice many of the things she admits are real. I have known people that use similar practices and rituals.
You can’t use the argument that “it’s not real” anymore. The author herself has admitted it.
