Of course, he thinks his daughter has been indoctrinated, but when I talked to her mom she told me that while she had never heard the word "therian" until Niece brought it up to her, Niece has expressed that she identifies very strongly with wolves since she was about 5 years old.
So sure, she learned a new word for it & found out that other people feel a similar way to her, but no one taught her to feel that way about herself, & it's a feeling/identity that has persisted for a long time.
