I am a biomedical scientist and can confidently say that a lot of things drive (and distort) science that have little to do with objectivity and a desire to discover/create something useful. And I think many therapists and therapy-related theories claim far more bizarre things than homeopathy as "treatment". I am certainly not surprised if someone who decides to be a therapist has other woo-wooish interests and offerings as well - it is kinda consistent.
