I’ve seen people talk about actors and artists that had a terrible time.
My own would be Anne Rice. She wrote Interview with the Vampire after her young daughter died of Leukemia. Then her husband suddenly died of a brain hemorrhage. I suspect her Christian, anti-fanfic phase was a result of mental illness and manipulation from the publishers, although I don’t think she ever apologized.
What genre fiction even fits the description you’re painting there lol, just seems like a strawman. Feels more like a manifestation of your personal dislike of people who like genre fiction or something.
